Tricks & Tips / Re: Alloy polishing
« on: October 08, 2015, 03:14:18 PM »
Thanks for your tips ans links, over the winter I will take the fork lowers off (and fit Progressive springs at the same time) to polish them myself, and also the alternator and gearbox covers too as time allows. Sod paying someone else to do a job I could do myself over long winter evenings.

I have a good rotary polishing mop / grindstone as well, unfortunately I no longer have a workbench to bolt it to.

Misc / Open / Preserving Nature?
« on: October 08, 2015, 03:05:07 PM »
So how do I 'preserve nature', like my sticker tells me to? Not run over wildlife? Miss the flies? Not go out on the bike? - Wearing a helmet and 'thinking safety' are a bit more obvious.

While we're at it, my CB750 k1's warning sticker is below the filler cap - shouldn't it be above, ie between the filler cap and the forks? - It seems that way in the parts book, but the sticker is missing on most bikes I see on the net. I'm a bit distrustful of the stickers that came on my bike, after noticing yellow 'Helmet Lock' stickers where there aren't any on a K1 - someone obviously felt compelled to use the whole sheet!

Misc / Open / Re: Clutch and master cylinder levers
« on: October 08, 2015, 12:57:46 PM »
IIRC from when I was Classic racing it was an ACU scrutineering requirement to have ball ended levers, to make sure noone got impaled by one in a crash.

No such requirement for the road AFIK, as has been said there are lots of old Brit bikes with pointy (steel) lever ends, but a lever with the end clearly broken off would be a fail.

I went the other way with my CB750 and bought the black rubber caps that fit over the balls, if I can say that without going 'Oo er missus!'

Clever how you bolted it to the garage ceiling like that!

Bit like the grey  cementy stuff of the inside face of chromed tinware type points covers.

That I do have, and I thought it was some unsightly repair or bodge by a previous owner!

Do they make much of an audible difference? No sign of them on my motor, other than the holes they fit in.

They must be some use, or they wouldn't exist.

I had a look at them, thanks, they have the correct 6x12 bolts. also they have a pair of painted sidepanels - I thought they only did full body sets.

If I can get the right money for the K0 stuff, that would fund a new pair of painted panels (about £137, don't know what the postage is). What the colour match to my original tank paint is like is anybody's guess, but has to be better than me with a rattle can, or my mate continuing to make zero progress painting my replica panel.

1283
All the bolts ansd screws on my bike are new or replated, but at the risk of sounding sad and OCD, many are wrong, ie not original.

Ive replaced all the allen screws with JIS crossheads, but many bolts which should be 'number 8' flange bolts aren't - there's a bolt and washer with modern mumbo jumbo on the head. I want proper 'no 8' bolts, damnit!

When I get to shows and autojumbles I will be rooting around in boxes for these, but eBay only has job lots the same size, as far as I can see. Anyone point me at a good source? I particularly need 6mm x 12 for the airbox, 3 shorter 6mm bolts for the oil tank, and 8mm x 28 for the brake pedal. Then there's the big ones for the rear indicator / frame bracket.

I also need a K1 battery sidepanel in candy blue green (code AZ) - I have a replica that someone is consistently failing to paint for me, if I can bag a factory finish one that would be a result. I have a genuine K0 airbox AND a K0 battery side panel in the same colour to swap.

CB750 / Re: Clutch switch?
« on: October 05, 2015, 03:31:21 PM »
All back together and (finally) working, after much faffing about with connections and badly labelled wires. After ages staring at a poor copy of a K0 wiring diagram before I went to bed I realised what I had done wrong, dreamed about wiring it correctly, then the next day went out and wired it correctly first time.

The twin throttle cable is in place, I should never notice unless the throttle tries to jam open. I had to consult the internet for a clear photo when I realised I didn't know how the push/pull cables worked at the twistgrip end.

After much rechecking of the right indicator wiring connections I found my problem is that there is a 'knack' to the worn switch - it needs a good firm 'click' - a half hearted slide and it seems to 'stall' and stop working at all. Cleaning has improved it but spares to refurbish the switch aren't available. Here's hoping the MOT tester understands -as long as I know how to work it that's OK!

CB750 / Re: How long have I been in this coma?
« on: October 05, 2015, 03:14:20 PM »
Look at the price of early eTypes, 911's etc...

I just reinsured my 911, at an agreed value of over twice what I paid for it in 2013 - like the classic bike market these prices are fuelled by almost non existant ISA interest rates, no CGT on profits and dealers who ask seemingly mad prices and get them, much to everyone's suprise.

£52,989 seems a bit mental for a bike, (as well as a bit arbitary) even for a sandcast which is defintely the 'blue chip' investment. However I was at the Goodwood revival a few weeks ago, the prices and values of classic cars there were eyewatering.

Like with my car, some of us need to keep tabs on the agreed value we would get if our CB750 went 'walkabout'.

Driven by the same factors, ie money for investment looking for a safe home, sales of old and rare whisky are at a record high this year. Auction house Bonhams is holding a whisky sale in Scotland to tap into demand and a bottle of 50 year Glenfiddich will go under the hammer on Wednesday for an expected £15,000.

There is a downside to investing in Scotch - imagine waking up with a sore head and slowly realising you have drunk your investment portfolio after returning from a good night out to find there was no other booze in the house....  :(

CB750 / Re: Year Of Manufacture letter
« on: October 01, 2015, 01:25:02 PM »
I'm in the same boat as you, Chris. I waited weeks for Honda to write to me, with no stamp, to tell me they won't help. I'm now into the 3rd week of waiting for VJMC, but I don't like to hassle volunteers. I'm still frustrated while the weather is so good, to have another bike I can't ride. (I already have a collection of parts that would make a Harley Sportster, if only the engine wasn't FUBAR, and waiting for other people to pull their finger out).

What bugs me most is that armed with the frame number, 2 minutes on Google tells you what year my bike must be.

Sadly no photos, it was pre digital cameras, but post CB750s (RC45's). The one time I turned up at Croft testing with a camera, I was spotted by the team boss, who asked me 'Who do you think you are, a f£*&^%$g tourist?' Lots of stories, but many are NSFW.

I still have some cool team gear, including my red Honda overalls, with a hole in the knee where I crashed a team scooter into our Sprinter van at the TT. Phil McCallen told me off for riding recklessly which I thought was cool coming from him. I should have got it in writing. The scooters ran on Elf race fuel, just for convenience - so did the generator! A Honda dealer at the TT showed me how to derestrict the scooters, which involved plunging a soldering iron into the ECU at just the right place.

Honda had a big garage at the old post office depot, they may still use it for all I know. Each team had some space, Team Joey had a room, so did a bunch of bikes from the Honda museum brought over for the parade lap, including a six. I got quite upset by one of the Aussie riders there flying a large petrol driven remote control helicopter indoors while we were working - what could possibly go wrong?

I have a faded photo of the truck I drove for Haywood Racing's Formula Ford team - our sister Renault team had a 16 year old who had to live at the boss' house, and  go to school when we weren't testing, I was told he was 'the next Mika Hakkinen', In the half a season he was there, Kimi Raikkonen spoke to me once - when I asked him if he wanted me to get him some breakfast at Oulton Park, he said 'No!', and that was it. Even then you could see his talent - at Thruxton, where he'd never been before, he had to start at the back having done zero laps in practice after an electrical fault, he got up to 5th, sailing past his team mate, before his car broke down again. He left shortly after.

Still no sign of my dating letter, I'm hoping to get 'Candy' registered and on the road before the road salt season starts.

Cheers all, @ JamesH, yes it is the one Motorcyle Emporium imported, I bought it from a dealer up here in the North. Googling the wording on the ad, I even found the for sale ad when it was sold in Durban at the start of the year. No info on when it was restored or who by, but a lot of new and replated parts, it seems to have done very little if anything since. The engine runs very sweet though I gave it a full service anyway.

It came as a bit of a K0, K1 mishmash, even with non matching sidepanels and a K0 airbox, now up for sale along with the K0 battery side panel if anyone wants it. After toying with going K0 stylee, I decided bog stock as possible K1 (but in a rare colour) was the way to go, rather than something that screamed 'fake' to anyone who knows their CB750s.

As noted on another thread, I have later (K3?) handlebar switches, which is causing me problems rewiring after changing the 'bars for correct ones, currently I have a horn, starter, and one indicator, no lights.  ::)  Today I found colour wiring diagrams for the K1 and K3, hopefully I'll make some progress. At least the fuse didn't go 'phut!', or the smoke didn't escape out of the wiring (electrics rely on smoke inside the wires - let it out and things don't work any more). Why didn't I take photos? Somehow I thought rewiring would be obvious.  :( Someone tell me what the brown wire from the loom does, I can't see it on my diagram.

I've just bought the 2 nipple throttle tube and 'push' cable on the Bay of Fleas. I will check out the kill switch, if it's 'iffy' I'll leave well alone for now, unless a NOS one comes up at some time.

I have the 2 holes for the throttle cables in the twistgrip, with a second thread for the adjuster, so I'm still assuming that I am using CB750 switchgear. I'll check tonight when I'm back in the garage.

If reinstating the kill swich is as straightforward as that it will be a pleasant surprise, I'll need a multimeter on the swicth to see if it works Ok - my guess is that it was disconnected for a reason.
