Rickman build
captaink:
Anyway news on the Rickman:
The frame and nickel plate may be completed this week, won't hold my breath.
The oil tank and a few bits are at the powder coaters.
The cases are at the vapour cleaners.
The heads gone up to have new valve seats and valves etc.
I'm going on holiday for a week so and when I'm back the parts should all be done.
Regards Keith

These people talk about C3 and C4 rating.

markB on the sandcastonly site did this excellent table on the early CB750 engine bearings, and many remained the same throughout the models. I played safe, bought an 11k mile gearbox from the States and Genuine Honda output shaft bearings from Yamiya. If you have Excel installed click on the link for MarkB's table

Last of the engine ally parts came back today.
The head has gone off already and it its fairly likely that the top engine case will go off in a few weeks for new studs to be fitted.
As for replacing the Pistons and rings etc for new standard size it may be more beneficial to have the cylinders bored out to 836cc and use a big bore wiseco piston kit.the parts will be easier to obtain and less hassle.
Am I correct in assuming that the big bore kit will not need new rods or uprating anything else and will not require new cylinder sleeves just a rebore ?

I have info back from the engine guys who are doing the machining that the exhaust valve guides are shot as I could see myself and that these can be obtained from the USA and that they are the bigger F2 valves 31 & 34mm. They said there in good condition and re usable but I would replace them if there freely available.
Also had some powder coating back ,few brackets and the oil tank which looks really nice

Looks like a lovely finish on the engine cases / block in the background. Vapour blasted and painted?
