Honda-SOHC

Hi everyone,

I tried to get a reply to this one on the US site but surprisingly no response.

My 750 K0 was purchased with 40 odd K miles on the clock and had not been used for about 17 years so I never heard the engine running. I have a heap of new or low miles parts for it including crank, barrels and pistons and new genuine chains etc. The original top end I am sure has been replaced as it is in very good condition and there are seals on both inlet and exhaust valve guides.

Here is the question  -  I have quite a few parts from a K7 and F1 engine and these include complete clutch (with the double 'B' plate), shifter forks and shift drum. Since these parts were upgraded on the later bikes (as detailed in Honda Service Bulletins for better transmission shifting etc.), is it worth me using them instead of the original K0 parts? Obviously I would retain the originals for historical reasons.  Also are there any other 'upgraded' parts I should look at using from the later engine?

I bought a CB750 341 style rear fender from the USA for my UK K0 (I could not find a new 300 style one with the UK 4-hole lamp mount) and the chrome was in really good condition but had the usual slight surface rust underneath, which I wanted to remove. I was recommended to use a product called 'Deox-C' by a friend who runs a local engineering company. I dipped the fender in it for about 48 hours, as I was assured that the chrome would not be damaged in any way. I have to say that the stuff is magic  because it removed all of the rust but no base metal or Chrome. I think they also sell it in Gel form too. Don't know what it does to Zinc plating though but will try it out and report back. definitely brilliant for restoring chromed parts though.

Or does anyone know anything better?
