Fitting a B50 barrel

Will this work on a B50? or will the larger diameter oif top tube make it impossible?

Re: 1978 CCM Replica Build

Hello all, Just a quick update, the crank is now in for the second rebuild wooooo! So on further investigation we found the big end cage to actually be to wide, significantly enough that it appears the bearing was never truly rotating so with the rollers skidding on the journal and outer ring resul...

Re: Stuck in 4th

Just to let you know what I thought was a straightforward (relatively) job turned in to something of a nightmare due to the oil filter mod on this engine. The lower oil spigot is in the way of a screw in the casing, simple enough just unscrew the spigot. See photo Not that simple because the frame s...

Re: Stuck in 4th

I have dutifully followed your instructions as far as removing the split pin & quadrant shaft, but what about the return spring pivot bolt? do I remove it
or will the eye of the spring slide off it & won't that be a bugger to reassemble?

Stuck in 4th

My gearbox has always been a little stiff changing down from 4th to 3rd now it has stuck solidly in 4th. From what I read it is more than likely to be the cam plate spring, I also read in the manual that it is possible to replace this without removing the clutch etc. The manual only says it is possi...

Re: Cylinder head welding

I also used a pipe expander recently after trying all sorts of high temperature sealants which blew out almost straight away. The pipe expander works well, just expanded the pipe a little at a time until I achieved the required fit. I bought a set for £23 from here https://www.machinemart.co.uk/p/04...

Re: B44 clutch dragging

Put the plates 1 at a time on a piece of glass (a flat mirror will do) & see if you can "rock" them, turn them over & try the other side.
A slightly buckled plate will cause drag, change the offending plates, they're cheap enough

Re: kickstart spring

Solved it by cutting a slice of 6mm hydraulic hose about 4mm thick & sliding it over the end of the spigot against the spring & it will compress slightly when the outer case is put back on.
A very worthwhile mod I would think

When an oil filter is put in to the return oil line, would it be a good idea to blank off the original feed to the rockers & then tee off a new feed the other side of the filter? or would it make no difference either way (see my crude sketch below)
