Member 4 Sales / Re: Engine Oil label for sale
« on: January 05, 2022, 12:46:41 PM »
I just checked my photos from 2018 and discovered that my CB750 K1 had the later K2 sticker, nobody told me at the time!

Luckily the bloke who bought it didn’t know either  ;)

CB500/550 / Re: 1974 CB550 Summer Build
« on: December 23, 2021, 05:50:32 PM »
My Sportster has had an undersize plate from new - fitted by the dealer it was the only size that fitted between the mudguard and HD luggage rack. Like with the loud pipes (never been a problem, Harleys all sound like that), my MOT guy and I have an understanding that, if plod asks, it was obviously legal when tested, and I've changed it since.

I recently saw an advantage to side mounted plates I'd never though of - a chopper with one overtook me at speed just before the local speed camera. As he passed the camera he just casually put his left hand down behind him and covered the plate!

CB500/550 / Re: Black number plate or yellow?
« on: December 14, 2021, 12:20:21 PM »
Back at the time, I eventually (after getting away with it for a long time) got pulled on my 1977 Triumph for a black and white plate, you could buy a plate and stick on numbers from Jack Bottomley's in Salford. I used it because a (deliberately) dirty and undersize B/W plate was much harder for a cop or indignant passer by to read (no cameras then). In those days the cut off was meant to be 31/12/72.

I was pulled for my plate on a wet M6 by a Range Rover, he didn't notice the fact that I nearly ran into him because I had no front disc and twisted forks, I was recovering the bike home after an accident. I just got a bollocking over the plate, no further action. When I switched to correct yellow plastic ones, they kept splitting due to typical Brit bike vibration, I mounted them using rubber grommets in the end.

My 1974 Z1-A 'should' have a yellow plate to be original, but as it was in the USA then, and has used a B/W plate since coming to the UK in 1995 (a used plate was included in the kit of parts I built it from), sod it I'll use the B/W plate because I can, plus it's part of the bike's history, and cooler.

 I once noticed an outlaw type on a Sportster had a 'dry wipe' yellow number plate, and today's number of choice written on with a felt tip.

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).

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.

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.

Project Board / Re: Yamiya Tank and Side Panel Kit
« on: December 10, 2021, 11:45:35 AM »
The tax and postage on just a full set of shells for my CB750 from Yamiya was eye watering enough, but sometimes you have no choice these days.

An alternative to the body kit may be to do what I did - ordered a new replica tank and side panels from David Silver, and had them posted straight to Menno to work his magic. It worked out very well, but it was before the 'B' word that shall not be mentioned.

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.  ;)

I’m definitely going, but if I haven’t sold my Z1-A by then I’ll be taking that for the 50th anniversary malarkey.

If not I’ll bring the CL450 and hang out with you guys.

Looking good, if I didn’t already have one, I’d want one now!

I see what you mean about the seat, the cover texture  is much better than my copy, but it has a deflated look to it. I also notice I can no longer be smug about my tank badges having the ‘450’ on them, as now yours have too! Where did you find them? Mine came from California via France, a long story.

Of course Menno’s candy paint looks spectacular as always, as does my blue version.

I agree with what’s been said - nothing ever got rusty by being cold, it’s condensation that makes cold metal stuff in the garage get wet. I have one of those concrete garages as well, but I drilled air vents into the wooden gable ends. My attic used to get wet through, until I removed a large amount of old clothing stuffed into the eaves by the previous owner to cut draughts, never had a problem since. A customer who owns several houses told me that if he leaves a house empty he always cracks open a window to keep air circulating.

I have a dehumidifier in the garage but when it’s brass monkeys cold it doesn’t work at all. Sudden temperature change is the enemy.

As a kid I had a Venus Fly Trap for a while, I used to feed it flies and bits of sausage. I think it lasted as long as a fairground goldfish.

I use Dunlop K70s, for the blocky off road look without the downsides of knobbly tyres on tarmac.

They are Indonesian made I think, I found them on eBay.

I rev the nuts off it, by the way, there isn’t a load of torque but it loves to buzz along. Unless I miss a gear though, I doubt I’ll ever see the 9,500 red line. The carbs took a lot of setting up before she would run right, very sensitive to float levels, but once it was right I could forget about it, tickover is metronomic now, at first it was all over the place.

Strobing the timing seems to require an alternator cover with a hole cut in it, as these are rare (even damaged) I’ve only timed it static, but without problems so far. Common with many other 450 owners, charging seems marginal but I’ve never been stranded. She started first kick when the battery was flat after a long sleep in the garage.

Lovely bike! My mate describes my blue one as ‘still as pretty as a picture’.

You asked me about my pattern seat, although it is perfect shape wise, your original cover looks better with the more rugged fake crocodile finish. Mine has a cheap Chinese flasher relay - the part is shared with the CB750 sandcast, so only available at silly money.

The chrome has come up nice, I think it’s better quality than people give Honda credit for. I couldn’t find an early alternator cover either, they get beggared up by the gear lever every time you fall off.

I hope you get a chance to use this one, I ride mine all the time for local journeys as it’s great for buzzing through the traffic as well as the country lanes.

CB750 / Re: New to me CB750K4

I used to take the centre stand off every bike I bought, as a younger version of me rode it like I stole it, and usually fell off due to a lack of ground clearance.

Now I'm close to retirement age, that's no longer a problem for some strange reason.  ;)

CB350/400 / Re: Cross drilled discs
« on: November 16, 2021, 06:49:53 PM »
As a student I used to regularly drop in to Sports Motorcycles in Manchester to lust at the bikes there.

I've never seen it reported, and the bike certainly doesn't have them now, but I saw with my own eyes that the original NCR Ducati that Mike Hailwood rode in his TT comeback had radially drilled discs, ie the holes went from the edge to the inside of the disc. They were beautifully done, with countersunk holes and done at an angle making an airscoop effect, no doubt saving unsprung weight as well as cooling. Proper 'works' bike stuff.

I've never seen this in any article or photo of that bike, and no doubt when they wore out or warped they got replaced with ordinary discs, I've seen the bike a couple of times and there is no sign. However I know what I saw, so just recording this for the reference of google and internet could be useful to someone. I wonder if the current owner knows?
