Cylinder head gaskets 650CSR
After purchasing a new gasket set for my Matchless 650CSR, i have tried to fit new copper cylinder gaskets which seem to be to small and will not fit over the cylinder. I then tried to fit the new composite gaskets and guess what ! They don't fit either, yet there is a thin paper gasket that does fit, so what's the answered to what I do please

It could be that you've been sent '59 gaskets which have 76mm spigot hole. '60 on is 77.34mm.

According Steven Surbey, there are not copper gaskets for post 63 650. But I think it is not too difficult to ream the holes from 5/16° to 3/8°. Regarding the composite gaskets, they are not matching with the pushrods tunnels, since years ! If you don't ream them, the pushrods are rubbing against the gasket. Nothing is perfect...
