Hi everyone,

I am also struggling in camshaft and three rocker, I have the set of 312',bit when I will assemble the set, I found lots of  clearance between the rocker and the valve tip, @ on TDCC position, I have found the markings on the rocker adjusting spindles, and I have set them on standard position like exhaust side is on 7 o'clock & inlet one on 5 O'clock, seen in many videos, the gap is almost around 4.5mm,i don't have standard measurement of camshaft &  the rocker?

Can any of you people's help me with

That camshaft will repair Ash, get a replacement from DK but don't bin that one.

Couriers? a mate had a new head gasket delivered, they shoved it through his letter box - folded double!!!

Hi .. Make sure that,   if you have 312 rockers , you don't have the early camshaft

You can't mix 312  rockers with the earlier cams and vice versa. The earlier cams need the 286 rockers (312 rockers have 312 on the castings , 286 don't have anything other than production marks). One of the early cams is a 'fat' version (centre section fatter than late version)  and easily identified. But there is an intermediate one that looks similar to the later cam (K3 model onwards and very late K2) . Best thing to do is post pics of your cam and measure the base circle and lift if you know how to do that. Hope this helps

Ha ha .. that was a long time ago mate .. I kept the broken cam (DK told me to bin it and refunded me in full )  but I have a few anyway. I did think of boring the shaft and fitting a new spindle for the auto-advance mechanism.

BTW do you still need a CB72/77 cover?  Also my mate is looking fora CB77/CB72  cafe racer/sprinter if you see one about.

Haha sorry I didn't look at the original post date, it pinged up as Singal posted.

I would like to get a cover but not desperately, a damaged one will do, I know they are a bit rare in good condition with the kickstart hole undamaged, I don't need a kickstart.

On the parts side, I have a CB750 oil tank with some hoses free to a good home, it has a dent in the side.
