CB750 F1 Project May 15

Mirrors sorted I found an original set off a goldwing








The clutch disaster was down to someone previously not torqueing the bolts and they had drifted loose.


All Sorted and working fine

Next project the seat logo
Previously on the last 1 i did in 1996 I used gold leaf as the old logo was gold.
It would seem that some say white - silver should be the correct colour

If its silver I can use silver leaf  but it may tarnish?
Unsure at moment any views ?

Just goes to show how your memory plays tricks on you, I would have sworn that my 1976 CB750F (Red) did not have Honda written on the seat but I have just clambered up into the loft and there it was in gold, and verified by my better half as it was very faded. Here she is in 1976 (the bike not the wife)

Thanks Dennis - Gold it will be

76 Remember it well bought my first CB750 F1 brand new all nice and shiny
Traded n my 400/4 which i had only done 2000 miles on from new for the super bike of the times.
(Everyone else was buying the K6, so it had to be an F1 to be different -I do like the K6 though )

Like you had the I had trusty Belstaff Waxed Jacket
Who needs body amour  - it kept you dry.

Cheers

Spitfire:
Happy to help Keith, this is the one I traded in for the F1 the day before I took it in, my trusty old K1, wish I still had it now, I fitted a 900cc conversion and it went pretty well. The white paintwork came about as the tank was damaged so I had to fill and respray it.



Cheers

A bit more progress made over the winter months

Project 2 The Yellow F1 was playing  up so we changed the head  and rebuilt at the end of summer. Bike ran fine for 50 miles or so then started to leak oil from fins.
Not a bit but a fair drip rate.

We stripped back down over the weekend thinking it may the a poorly seated seal under the cam tower  "pontefract cake" or leaking through the threads of cam tower bolts. We had used standard gasket/thread sealants on all seals, but obviously this was no good in this case.




Sure enough when stripped down the seal "Pontefract cake had distorted/beveled and would seem to be the cause of the issue. I would think the seal had moved slightly during first rebuild and obviously you don't know till you run the engine.





Replaced,resealed and rebuilt started up today no oil leaks and sounding sweet.

We also balanced the carbs and whow what a difference it made to responsiveness of engine.
