Hi,
I am restoring a 1949 B31 and have looked at the rear sprocket and decided that it is not good enough, can any body tell me where to buy a new one or do I have to machine off the old teeth and weld on new.
The rear drum is not currently attached to the hub, I am assuming from what I have read is that they were riveted on, can you just use bolts or do I have to make rivets?.
Thanks for any advice.
Cheers
Andy
