Title: 1975 CB750 P2 Police Bike
Post by: JamesH on December 10, 2021, 12:42:41 AM
So, now that the ‘68 CL450 has finally ‘had it’s turn’ I thought I’d start work on this ‘plod’ bike that I’ve had for a few years now.

This is an ex-Saudi CB750 P2 - and let’s just say it’s going to need a LOT of love and attention.

This is going to be a slow-burner over the winter months, especially given the amount of painting required..

Anyway, as they say a picture paints a thousand words, so those of a rust-averse disposition best look away now…

Having owned just one white vehicle in my lifetime my experience has been that white  tends to magnify any corrosion rather than hide it.

Hopefully the bulk of it will be just surface cosmetic rust as per most of your pictures.

I think the police bikes look great. Because everything else is plain white, the engine and exhaust, the CB750s best features, really stand out, and that huge speedo is epic! The radio / doughnut box on the back looks handy.

I just read that Honda exited the police bike market quickly, after a LAPD cop, trying a disk brake for the first time, fell off, broke his elbow and sued Honda! As a teenager, my CB750 got pulled, late at night, by a couple of Norton Commando Interpols, but only because I slowed down to see who was trying to keep up. 

I've had a couple of old white cars, and can recommend white Duck tape for the rust patches that show through.  ;)

Lol - that’s it. I’m not going to bother painting the frame then - I’ll just get a few rolls of white duck tape and be fine with it…

Well, the engine rebuild actually took place over the last few weeks (in advance of a build like this I always like to get the engine buttoned up an ready to just put back in when the rest is ready).

The oil pressure switch wire (with the horrible red crimped connector) is just there for testing - I have a new Honda wire and moulded rubber cover to fit..

Looking nice…

I was about to whinge about that nasty red connector (hate them with a passion) when I saw your edit, James. I once spotted a CB750 bottom end for sale at Stafford, and managed to negotiate to just buy the rubber boot for the pressure switch, as I couldn't find one anywhere.

Regarding slowing down for plod, the one who caught me up first I actually knew, he'd been trying to join our bike club as he was a keen biker, but we eventually voted 'no' because not all our bikes (or cigarettes for that matter) were strictly legal (this was the 1970s). We had to wait a while for the other, slower, plod to join us, the one I knew actually apologised for the fact that he'd have to 'do' me, because his colleague had watched it all. The summons was suitably vague, 'exceeding the 30 limit' without mentioning the stupid speeds we'd actually been doing, what size bike I was on or the struggle to catch me up. I don't think that alcohol was ever mentioned at the time either, but I was on my way back from taking a lady home after a visit to licensed premises, enough said.

That engine looks brilliant James will be interesting to see what you do with the frame colourwise - I like the white tbh - probably a genetic link to my past employment.

A slight tinge of Ivory will make the frame look even more solid.

I’m impressed that the kickstart shaft is replated  (or new), lazy ass here tends to just paint the ends with silver undercoat and clear laquer.

Attention to detail.

Talking speeding how about 2 plod BMW chasing a Z1000 for 7 miles and only catching up, outside county hq, because of traffic.
Severe bolocking as they said they were doing 90 and i was dissapearing into the distance but they made the mistake of telling me they didnt get my number at any time till i stoppef!
By the way the truncheon is in the LH panier as one of them had to use it to clout the leaking carb

Looking good James  :)

I stripped a couple of NOS Honda Police speedos recently.

There is a little solenoid inside, which when it gets a 12v  signal it throws a little pawl thingy into a fine toothed gear wheel. This locks the speedo needle at the desired speed ..presumably to show to the speeding motorist that he has exceeded the legal limit.

Back to the Police resto.

Managed to grab an hour at lunchtime to lay out the various parts I’ve been collecting over the years for this specific build. If you though K0 / Sandcast parts were difficult to fine NOS, think again. Think Unicorn bitcoins..

Anyway, enough of the shi* analogies (Dave’s way better / more entertaining at those).

Looking down, I realise there is a serious amount of £ on the floor in front of me - a scary amount in fact.

Ash - you absolute legend. I was literally looking at a barely-legible wiring diagram earlier, trying to work out how the ‘meter stop switch’ is actuated / works… I’ll need to study the diagram in more detail when I strip / clean / repair the loom.

A manually operated proof that you are speeding.  There is a whole world of error/ judgement/ corruption in there. I wonder if the speedo evidence was admissible in court?! Quite likely if it was the seventies..... admit it or I'll punch you ...I confess..

This is going to be SOME Project ! I love the old Honda Police Bikes (The Kwackers too.....as the CHIPS TV show was a regular watch for me back in the day).

I was wondering if you had the rear wheel driven siren as I was going to volunteer to assist.....having successfully emptied numerous barrack rooms in the early hours with my very good impression of a Siren in my TA days.......for which I got a good hiding off the lads......all part of life's rich and merry pageant !

Can't wait to se it progressing....no doubt it will be just as good as all your spectacular rebuilds, but it will probably make a more 'arresting' sight !

I find the 'lock' mechanism fascinating, despite Andy's doubts re evidence, this was about as hi tech as it got in those days before speed cameras.

Somewhere I have a Smith's Chronometric originally off a Norton Interplod police bike that I rebuilt as a 750S, it has a lead seal and an initialed label, so that if challenged Plod could state in court when, and who by, it was last calibrated.

I wonder if the speedo evidence was admissible in court?

I had my day in Ruthin Magistrate's Court once, arguing that if the police car chasing me soon caught me up and passed me before the red 'POLICE - STOP' lights came on, it must have been going considerably faster than me, and therefore the reading on his speedo wasn't the speed I was going. I should have paid a solicitor, as it was I represented myself, the copper was 100% flummoxed by my argument (I had brought along a witness, overtaken on his bike by the cop car as it chased me) and had no answer to it. British / Welsh justice being what it is/was then, it made no difference except for making my fine higher. The cop was outside he court sat with his mate in a cop car, laughing as we walked out, no doubt hoping that I would commit a breach of the peace of some kind (I was sorely tempted).

This reminds me of the day when I was coming home from Chester on my CB750KO and I saw a police bike in front of me so I slowed up and he waved me over so we pulled up to the side of the road.
He wasn't a policeman but a mechanic doing a road test on a bike that he had repaired (Norton) and asked if I would come back to the garage so he could have a look at my bike as they were pretty rare back then.
What followed was a high speed dash to his base in Bromborough with me tagging along behind him at highly illegal speeds, the bike caused quite a stir at the garage with them all complaining about their bikes.

Cheers

Big pile of CB750P parts dropped at the blasters to be blasted and primed, prior to refinishing with 2-pack (2k) semi-gloss white.

Managed to take the NOS rear top box to my local Automotive paint merchant who did a spectrograph colour mate - Fiat Bianco 224 seems to be the closest OEM White - so that’s what I’ll be going with.

Will be a few weeks hiatus over the festive period, so next update will likely be 2/3rd week in January..

Does anyone else watch the reruns of CHiPs on TV? (Channel 96/ Forces TV on my TV).  There are usually some great shots of classic bikes and cars in the background or as part of the plot.    I was channel flicking last night and it popped up with an advert showing a grey-haired Ponch and a slightly tubbier Jon.... then it told me it was CHiPs 99 and they ride BMW 1100's rather than classi Kawasakis. Nothing is sacred!

Nothing is sacred!

CHiPs was essential Saturday evening viewing for me as well Andy (as it was also for Alan by the sound of it :)). I was 17 and riding a CB160 and could only dream of a big Kawasaki and going to California but living at home in a rented house and having no money it was going to stay just a dream. 25 years later I was riding a Harley on the same roads in California and dating a girl from Santa Monica! None of it lasted very long but it was a great adventure at the time.

The two main 'stars' of CHiPs actually didn't get along very well. Erik Estrada wanted to be in the movies. Anyone who followed speedway at the time will be aware that Bruce Penhall won the world title at Wembley in 1980 and won it again in 1981 in Long Beach. He had secured a part in CHiPs sas John's younger brother. The scriptwriters wrote the world final into the story. When he won the title he retired there and then to concentrate on his acting. The riding, chase and crash sequences of CHiPs were all filmed on the Glendale freeway that was under construction at the time.
I think I watched too much TV and needed to get out more ::)

So has been a quiet few weeks drinking / eating too much and waiting for a few things to come together.

Collected the frame and painted cycle parts from my painters yesterday - and they’ve done a lovely job. The colour match is 90% perfect to the NOS rear carrier / top box that was used for the colour match - so I’m pretty happy.

Just waiting for rear hub to be re-lined so I can get the wheels built and start assembly and get the engine in and get her back on her feet..

I'm looking forward to seeing this one finished, as I've only ever seen old photos of the P2.

Interesting that it came from Saudi, I remember seeing a bunch of nearly new white Triumph T160s in Sports Motorcycles. Apparently they had been sold to Saudi Arabia as Police bikes, but being Triumphs had sadly ground to an inevitable halt and had been left wherever they broke down. The prospect of having your hands chopped off for the theft of police property may have helped prevent them from being pilfered at the roadside. Being such a dry climate, they were worth saving, and had been brought back to the UK (I don't know who by) and recommissioned by Triumph.

Maybe yours has also had a long sleep in a hot desert.

Minor progress today on the wiring loom. The existing loom was beyond repair, so I decided to modify an OEM K5 loom to serve as the basis for the replacement loom.

The only difference I could find between the stock loom and P2 (‘75) original loom was the provision of a switched positive feed that runs the entire length of the loom front-back and T’s into the ignition switch (where it gets it’s switched feed from). The simplest solution was to cut this out from the old loom and ‘graft’ into the new loom.

The P2 loom also uses a square connector for the unique police ignition switch (which has 4 positions). This has 5 rather than 4 terminals in the loom—>ignition switch plug (the 5th is the additional switched positive feed which is a red wire with a white band at each breakout point).

I’ve also been searching for weeks for some OEM silver-grey glossy PVC harness sheathing in 18-20mm ID for the headstock end of the loom. The seller in the US only has up to 12mm ID. In the end I gave up as I need the loom in the next couple of weeks as the build accelerates.

So I’ve had to think laterally/innovate a bit here with silver-grey PVC heat-shrink, which luckily turned out pretty well.

Overall was a 2-3 hour conversion process. Photos should tell the story.

As always, amazing James. Who tho’ will be a likely buyer; can you use this on the roads? (Or would a museum likely buy it?)

Here in Brisbane, and only a couple of miles away this has been on Gumtree for a while now; a stalled project it seems… (£3650 ‘ish)

No it's like the handlebar switch the 500 uses for switching the lights on but I don't think it's one of those as the wire colours are wrong IIRC

https://www.ebay.co.uk/itm/224548038637?hash=item34481b27ed:g:A3QAAOSwzj5g~qPX

Not sure if it's for your model police bike or some other model. Thought of you straight away.

Thanks Ken. The patrol light switching is dealt with on the handlebar switch on the P2 model I think. I’ve not really studied the wiring in huge detail yet.

I think the switch you linked to is for a 550/750K (78) police model.

Well, I been thinking about this day for 3-4 years now, and finally have the engine back in the frame. She literally slotted into place perfectly - the easiest ‘re-insertion’ of a 750 engine I’ve ever had.

Luckily I had a new points cover in my stock pile - just checked the DSS price and (drum roll) - £360. Yes, £360. 3. 6. 0. British pounds. What the f*** is going on there..?

It turns out the NOS foot pegs came out of the sale of John Wyatt’s estate, via a nice chap who is helping Johns widow sell off his bike related stuff and doing so in a really fair, ethical and transparent way which is a nice touch. Thanks John for keeping hold of these over the years

Anyway, have made the progress I wanted this week - having a week off next week - so next update will be the following week.

So has been a ‘slow progress’ couple of weeks. Came back from Skiing and promptly got the ‘Rona, so that held progress up quite a bit.

Also, quite a few of the electrical component refurbishment jobs are REALLY time consuming - restoring the original rectifier took 3-4 hours on its own, a couple of hours restoring the pilot light indicator ‘brushed’ plate, building up the rusty seat catch etc..

Anyway, all of the major electrics are now installed. The ‘silver’ heatshrink on the headstock was a complete waste of time as i feared it may be - the heatshrink was way to brittle and would have cracked within a few miles of use, so I striped it off and the loom will just have to remain black sheathed in the headstock area. A small concession really, but it was worth a try.

NOS ‘white’ rear plastic inner muguard was very carefully fitted, rear painted guard fitted and light bracket installed with wiring.

Rear indicators were also fitted and wired up.

Battery and tool tray fitted with new rubbers and new battery.

The rear shocks were new items, but they were stripped into component form and the shrouds were stripped of chrome, colour-match painted, and then reassembled onto the shocks. Again a 4-5hour job. Getting the details right on a build like this is hard, time consuming work. But I know the end product will be worth it.

Rear hubs came back from polishing after Graham kindly re-lined the rear hub after much arm-twisting (and cash).

New bearings have been fitted to both hubs, ready for the wheels to be laced and trued before new continental tyres go on them.

I’ve been saving a pair of NOS Honda oil lines for this bike, as she deserves the best. I’ve also saved a set of NOS Honda HM341 exhausts for the bike. The parts bill for this bike is going to be bloody eye watering


Next job will be to fit new bronze bushes to the swingarm and get that fitted, lubed and adjusted.

Oh, I also have had to rebuild the original speedometer (damping action was fine) with parts from the NOS speedometer I had - the drive mechanism on the NOS unit I had wasn’t correct for my particular vintage of police bike.

I suspect Honda tooled-up for the shorter Police seat base (which is base on the early K0/K1 seat pattern) and carried the design through from K0 to the later models to avoid having to adjust existing stock. Just my theory anyway.

Did Honda assemble any CB750 police bikes or was it done via a third party with Honda supplying the parts.

I know that Honda police bikes in the UK were done by Honda Dealerships or third party contracts.
All the BMW police bike were converted by Mottingham Motorcycles in the 70's / 80's. And all the dominos pizza Honda's were converted and sold by Grafton Motorcycles in wolverton. Never found out who did the Honda CD250 police bikes. We have one but, it was sold to the police, never converted or used by them.

Thanks Davs - intention is to keep, but I'm wondering if I'll ever actually stump up the courage to ride it, or deal with the inevitible interest from 'plod' on every ride-out. Realisticlly I think it'll be sold at some point in the future - but it won't be cheap...my aim is to end up with a restored UK 750 K0, Early Sandcast (I have #820 waiting in the wings), a GL1000 and a modern bike. The rest will be sold...I've also stopped buying bikes now lol...

Ha! - you're the second person to ask me that question and the answer is it's in the correct factory position. I the contrast of teh black cable against the white paint of the frame draws your eye to it - but it's the factory position..good spot though lol.

Top box, rear ‘bumper’ and rear lamp now fitted. Just need to secure the bumper to the rear fender with correct shouldered bolts / acorn nut.

Rear shocks test fitted (lol).

Original bearings cut out of the swingarm and popped the phosphor bronze bushes in the freezer for an overnight cool.

Front forks assembled and just waiting for the top nuts and they can be filled with 10W fork oil and the front end assembly can proceed.

Rear brake plate also assembled with new shoes fitted.

Bit more of a progress update on the Police bike:

Wheels have been rebuilt - going to the local shop tomorrow for a pair of new Continental RB2/K112 tyres, new Michelin tubes and rim tape - the Conti’s are my go-to tyre choice.

Swingarm is now fitted (forgot to photograph the new bushes and new ‘collar’). Such a nice feeling putting a new set of phosphor-bronze bushes in with a new Honda ‘collar’. Smooth as butter, zero play, and fitted nicely back into the frame and torqued up. Freshly greased that’s one less job to do.

Rear ‘bumper’ now fully fitted and top box fully secured. Need to make up a jump-lead for the earth feed from the box to the loom.

Front end is coming together - forks fitted with new Honda gaitors, along with the ‘repainted’ fork ears that were rejected first time round.

Oil tank has been cleaned internally, fully repainted externally. Fitted perfectly with the NOS Honda fuel lines.

Moving on to the front brake calliper and master cylinder next.

Thank you to everyone who’s taken the time to comment and feedback, it’s really appreciated.

Small progress this evening - the headlight bucket has now been fitted and had to convert the Honda indictors to a ‘2-wire’ setup to provide the earth they would normally get on a 750 via the stem.

Wheels had the new rubber fitted today and are ready to go back on the bike over the weekend (time permitting).

NOS HM341’s hanging ready for installation.

This project is fairly taking shape. Looking forward to more! Speaking of losing something, I lost one of the small rivets off the VIN plate when I was putting it back on to frame, after being so chuffed to have salvaged them in the first place. But amazingly after the third day of looking I found it and thankfully it is now fitted where it should be. I have lost much bigger things and still not found them.😂

I've lost a bag of around 100 mixed crankshaft shells for the 500/550. Put it down around 20 odd years ago and no idea where they are now, the wife might have thrown them out, as wifes do.

An extremely small Japanese mechanic for when the bike breaks down or needs a service, unfortunately he died whilst in there and James hasn't been able to source a NOS one yet.

. I once worked on a project with Toyota, developing one of the last commercial IDI (indirect Diesel Injection engines) for production. I was responsible for the design of the pre-combustion chamber, the last iteration of the Ricardo ‘comet’ chamber design.

The project team in Japan sent us a Fax, in response to my request for an EEPROM programmer to re-flash a new engine calibration onto the development ECU - and it literally had one line that I’ve never forgotten: “We are dispatching Inoue-San”.

My equivalent counterpart in Japan was called Mr Matsudo Inoue (hence Inoue-San) and based on the fax I was expecting him to arrive in a box shipped by DHL .

2 days later he arrived at 9am promptly, spent 1hr reprogramming the ECU with the supplied calibration data-sheet, left us the EEPROM programmer unit so we could do it ourselves, and then buggered off back to Japan.

Possibly one of the most bizarre (but quite efficient) business exchanges I’ve had .

Here’s the latest instalment…

Rear end is pretty much finished - I’ll probably need to sort a chain with an extra link (as it’s running a 48T rear sprocket), or I may just go for a 45T sprocket.

Just need to drill the rear fender and fit the rubber ‘fender extender’ and will re-focus attention on the front end.

The front fender is loosely fitted but I’m waiting for a few bits from CMSNL in Holland to arrive before I can fit the handlebars, front fender stays etc.

Fitted the NOS brake hoses, the upper hose being slightly longer to accommodate the police ‘high’ bars.

Oh and I had to 3D print a test piece for the missing (and NLA) siren actuator spring holder. Luckily CMSNL had a photo on the website that I was able to use as a general reference. After 3D printing the sample it dawned on me that the overall shape looked familiar. The small metal plate that comes mounted to the underside of most Honda CB front master cylinders is almost a perfect outline, so I’ll modify one of those for the final item. All good fun ha ha.

But, at last she’s back on her feet and really starting to ‘take shape’ now.(https://uploads.tapatalk-cdn.com/20220311/ee2da02b362b885deba788e646ad207c.jpg)

Thanks mate - yeah familiar with the ‘DigitalPizza’ bike. Had the same thoughts on the wings lol. And yes, that’s the same bracket - hadn’t spotted that before..I still think it would look nicer tucked away behind the shock so I may relocate later on.

Further progress on the CB750P today.(https://uploads.tapatalk-cdn.com/20220314/7753a1e967836c4de629dd84077495a6.jpg)


Exhausts fitted, rear crash guard hoops fitted, front fender stays fitted, rear fender extender fitted, front brake assembly fitted.

Also test fitted the front engine guards.

Rear siren roller drive retaining spring fitted. Will re-engineer the drive bracket at a later date once the bike is finished.

Tomorrows job is to wet-sand the fuel tank and apply the decals before returning to the painter to clear.(https://uploads.tapatalk-cdn.com/20220314/842318a000d6089d2e6bdf77c63ea46d.jpg)

…how is the siren engaged James? Could this be achieved at speed? What min speed is necessary for it to work?
Honestly it seems a bit Heath-Robinson given the era, I’d have expected a power off-take from the engine …. eg the SOHC, or perhaps electrical + uprated ALT. Intriguing! (Tho’ it’s apparent a very high siren drive RPM was necessary given the massive ‘gearing’…. bet the top speed bled off pretty quickly 😂)

Having seen it mentioned in two consecutive posts, there will be young people out there wondering what or who the hell was Heath-Robinson?

Lovely build as expected, most of us don't have a load of NOS parts stashed away for future use, especially a genuine exhaust set, or a Police speedo for that matter.

Thanks for the encouraging words / comments / feedback.

With the words ‘Heath Robinson’ ringing in my ears, I had a spare hour over lunch so decided to mock-up a replacement for the siren drive to test-fit before committing  the design to metal.

I’m lucky to have access to a ‘fablab’ in the studios where my business is now based, including an array of ‘Prusa’ 3D printers. I was trained how to use the printers last week, and this was a fairly ambitious ‘second print’ so I was fully expecting it to go ‘tits up’.

So working from the existing siren bracket and some ‘guesstimated’ dimensions from photos found online of the ‘correct’ 750 bracket (turns out mine is for a 500/4 police bike) I designed up the unit in 3D (using Fusion360) before exporting an STL file, ‘slicing’ it up in preparation for 3D printing, outputting the G-code and then 3D printing in PLA.

Having removed the support material, have to say I’m pretty chuffed with the result.

However, the rule of ‘measure twice, cut once’ applies here (well actually check your design twice, 3D print once lol).In my haste I managed to place the design for the return spring hole on the wrong side (realised after printing). So I’ve adjusted the design and set one to print overnight.

Will test fit tomorrow evening to see if it’s a better solution than the 500/4 ‘bent arm’ design, before manufacturing it.

There were actually 2 machines free at lunchtime, so I ‘hedged my bets’ and set off two of the machines printing (one in black PLA and one in Grey PLA). That’s why the ‘finished’ part is black - that was one of the two prints..both successful (apart from the design cock-up - see below).

Managed to get a few more hours on the police bike today, and she’s really starting to come together.

Siren test fitted and patrol lights fitted and wired. I’ve decided to run a red/blue patrol light setup for now (as opposed to the double red US setup). Not sure if this will stay this way, but is fine for now.

Master cylinder refurbished and fitted. Both controls have been refurbished - can’t fit the Lh switch until the clutch perch and siren lever perch come back from straightening and polishing.

Hit a snag with the tank paintwork - so that will be a couple of weeks away at least. What is it always the paintwork lol..

Anyway - progress photos below:

Just remembered James that back in the seventies I made a model of that exact same police bike, it was made by Tandy or something like that. It was on display in my mums display cabinet for many years, only the sight of the lights made me remember it. I wonder if it’s still available?

At 84 pounds it might be cheaper to buy one from James when finished!

Your correct about the blue light. Your not legally allowed to have any blue light on a roadworthy vehicle. Even the cruisers with blue LED's under the car get booked. Maybe don't wire it up.

You are okay with a blue light until you switch it on - until then it's not really a light!
From my memory the legislation that covers emergency vehicles takes about a lamp emitting a blue light being restricted by the colour the lamp shines.

No, that's incorrect. From the relevant legislation:
"Only emergency vehicles can be fitted with blue flashing lights, or anything that looks like a blue flashing light, whether working or not."

 There was a gov petition some years ago about blue lights on historic emergency vehicles and it was generally accepted they have to be covered when on the road. Strictly speaking they should be removed. Likewise the word Police should be covered.
This is the gov response to the petition.
 Blue warning beacons are intended to provide emergency vehicles with a means to inform other traffic of their presence and to assist in their safe progress through the traffic when responding to an incident. Whether or not switched on, they help to identify vehicles that are being operated by the emergency services and so the general public can have confidence they are dealing with a genuine representative of the service.

The wider use of these lights will eventually undermine the benefit they provide to legitimate users, hindering their ability to respond to an emergency and potentially endangering the safety of the public. Deliberate misuse of blue beacons to give the impression a vehicle is being operated by the emergency services could also increase if strict controls on their fitment are not in place.

We do not expect genuine owners of preserved emergency vehicles to abuse blue lights fitted to their vehicles. One solution would be to permit covered blue beacons, although this could potentially increase the misuse by non-emergency services. A change to the regulations must also be enforceable and in many cases it will be difficult to determine whether or not a vehicle is a genuine preserved vehicle or has been modified to deliberately deceive.

There is no simple, quick fix, of the regulations that avoids our concerns over misuse. The current regulations permit preserved emergency vehicles to be used with blue lights at shows provided they are removed before the vehicles are driven on the public roads and so we do not intend to change the regulations at this time. We will however explore with representatives of the police and other interested organisations whether there is an acceptable solution that can be considered for future implementation.

Evening all.

Progress on the Police bike has been sporadic and slow, whilst I’m waiting for a few bits to come together..you guessed it, the bloody paintwork. Why is it ALWAYS the sodding paintwork that holds up these projects .

Anyway, have got the front end finished now, and carbs fitted and we have a running bike. She settles down into a nice smooth, quiet tickover - so I’m bloody chuffed.

The headlight ‘nacelle’ was a bit of a challenge to get a headlight rim to fit smoothly, but managed to get there in the end.

I’ve also wired up the patrol lights to a flasher unit I found in the US - yes, they’ll be disconnected for road use but if I ever show the bike it’s a nice little ‘show trick’.

I’ve also been at the 3D design/printing to mock-up the missing bracket that guides the siren cables to the rear drive bracket/roller. It’s amazing what you can conjure up from a couple of photos from the internet . Had to redesign the first effort and ‘thicken’ it slightly; second time lucky.

Have been in touch with Venhill who have agreed to manufacture a clutch cable in grey to my specification - the one I bought from CMSNL two years ago was about 16” too short..def a spec savers job there lol..

So will be a quiet couple of weeks whilst I wait for the paintwork to get sorted, then I can button this one up and go out for a spin / get arrested by the local plod for ‘flashing’ :-).

So the bike is pretty much finished - just awaiting finalisation of the tank and side cover. I have the unenviable task of fitting the decals later this week before the tank is clear coated by the painter.

Anyway, airbox is now fitted, carbs synchronised and she runs really nicely.

Have finished the siren installation; the proof of concept 3D printed roller drive bracket was a great guide for my local welder who modified the 500/4 bracket to match my design.

Correct length clutch cable sourced and fitted.

Revised design for the 3D printed siren cable clip fitted - I’ll need to make a final design change to this but it’ll do the job for now.

I also managed to source a ‘low profile’ blue patrol light to match the red unit I had with the ‘clear’ lens. So I’ll fit these reflectors to the bike tomorrow at some point.

Also fitted and aligned the NOS seat and very please with how she’s looking. The paintwork will be the icing on the cake once ready.

Amazing work - lovely.

‘Concerned’ 😂 at the RPM at 80mph of the siren drive cable. On the assumption of no spindle gearbox at the rear-wheel off-take, and using a wheel diameter of 56cm and the spindle dia @ 4cm….. I reckon the cable would be spinning at 17000RPM.

Imagine that coming loose flailing about your right knee and ankle …. or worse snaking towards the family jewels as you pursue Jonny Burglar 😱.

By contrast, at 80mph the speedo cable is spinning @ 3500RPM, and the Rev Counter cable abouts 2400RPM.

Maybe don’t try it James … certainly keep the cable well lubed!

Happy to stand corrected… I hope I’m wrong!

Thanks for all the feedback. It really helps and keeps spurring me on over the finish line.

Picked up the fuel tank and managed to grab a couple of hours at lunchtime to work in the ‘clean room’ (aka the dining room table) to apply the decals to the tank.

This is the job I’ve been most dreading on this project, as I’ve never (successfully) attempted decals with this level of compound curvature.

Procedure was to very lightly wet-sand the base coat on the tank with 1500 wet/dry, to give a good adhesion bed for the decals.

The decals are best applied ‘wet’ with a spray bottle with a small amount of washing up liquid, which gives time to position the decals before pressing them down with the squeegee. Patience is the key here as the decals come in 2 parts and need to ‘line up’ in two locations but with two pairs of pinstripes.

Anyway, 2 hours later and it’s done - it wasn’t straightforward but I stuck with it and it’s pretty much spot on.

Back to the painters tomorrow for 2K clear and I’ll be ready to fit and wrap this project up…

Cheers guys - smashing a pint of IPA and having a play with the design of the siren bracket in CAD to see if I can use a 3D printed part and still tighten the rear upper engine bolt without crushing the 3D printed plastic material (PLA).

Current thinking is to recess an M10 washer within a recessed pocket and use an M10x25 washer under the nut to transmit the load. I’m sure there’s a better way but the beer is flowing ha ha..

Evening chaps.

Finishing touches applied to the bike this evening, after receiving the tank and side covers back from my painters.

In the past couple of weeks I’ve swapped out the patrol light lens’ for the earlier ‘clear’ style - personally I prefer the look of these.

Very pleased with how she’s come together over the past 14 weeks. It’s been a long haul since buying her back in 2018, but I guess good things come to those who wait.

Family ‘staycation’ means she’s going to stay put for a couple of weeks before I can do some shakedown tests. But it’s been worth all the hours and effort that’s gone into saving her.

Thanks for the comments and feedback along the way, it’s been greatly appreciated.

I think that's the best one you've done so far James, great build and so unusual. Only ever seen one and that was a model kit.

You've annoyed Deltarider though, he hates polished stuff that wasn't polished before, and chrome for that matter. Personally I really do like that, it's so unique it just appeals to me and your attention to detail is superb. For me that's what makes a build, get the little details right and it makes the final result so much better. You must have been collecting parts for this build for years, no way you could do that in 14 weeks without a vast store of acquired parts, sometimes takes 8-10 weeks to get a part from Japan.

I'd say you've got to keep that one, you can buy another K0 quite easily but finding another like that would be extremely difficult. If DS comes sniffing for his museum tell him to take a hike  ;D ;D ;D

Thanks for all the comments / feedback along the way. Massively appreciated and it’s been a joy to restore the bike.

I’ve got a difficult decision to make. I think I’ve come to the realisation that I’m more of a serial restorer than a rider - and that’s a hard admission to make and say out loud. It may well be time to flip that dynamic on the head and focus a bit more time on riding / enjoying the bikes.

I’ve stopped buying bikes, but I still have several waiting in the wings to be restored or already partially in ‘progress’  - in particular a trio of dismantled UK 750 K0’s (from the second batch) that I’ve had for several years (one of each colour)..and they’re up next for the next build slots.

It’s difficult to justify having so much investment ‘tied up’ in a single bike and putting my cards on the table-  I’ve just been made a very significant offer for the bike (unsolicited) which could be a bit of a game changer for me.

I said at the start of the year I need to get the bike collection down significantly (not least, storage is a big issue) and focus on some other projects that I’ve been putting off at home, so much as it pains me the Police bike may well go.

There’s also the small matter of the ‘attention draw’ this bike is going to yield when riding it - I’m a bit of a ‘show off’ at the best of times, but I’m still not sure I’m ready to be seen in public ridding this bike lol..

Anyway, time will tell - I don’t actually need to sell any of them, and I’m just extremely fortunate to have had the opportunity and pleasure to work on restoring such an iconic bike.

I’ll keep you all posted - and will start new threads for the next restorations as they begin..

I repeat James, that is by far one of the coolest bikes I have ever seen. Your finish is simply unbelievable and as Ken said, the attention to detail completely makes the end result so fantastic. Well done in a MASSIVE way.  ;) :)

Well if that's the case maybe selling it to DS for his museum would be a better choice.

If you think of doing that I'd stipulate that in the event the museum closes etc you are given first choice to buy it back at the same price as he paid you for it. Or rent it to him for display. I reckon DS would try and sell it later using some excuse of other, he's driven by the need to make money IMO.

It should be appreciated for what it is, a unique bike with a unique story.

Well, the decision has been made over the weekend and the bike is sold and was collected yesterday.

Many thanks for the feedback, compliments and opinions on what to do. Ultimately the bike needs to be seen / used, and on reflection I’m the wrong custodian to do the bike justice in that respect.

I’m about to start with the rebuild of my two UK K0’s (AYO 63H and AYO 64H) so will start a new thread on those very soon..

James

Sometimes when you restore a motorcycle to the high standards you always achieve James you know if you were to keep it you would only see it deteriorate every time you used it. I know bikes are meant to be ridden but sometimes and especially when only you know the amount of time, effort and money that has gone into the build it is hard to ride it any great distance considering our changeable weather! I agree with you, in these circumstances it is better to sell it on and put the money into the next project. It was a fantastic build and certainly one that will forever be noticed by whoever rides it.
Im looking forward to the KO builds :)

now now Graham. The thought did cross my mind. At least the top of the saddle was black rather than white, so I could have got away with wearing my assless chaps. Oh well, one for the future now I guess.
