I am rebuilding my Dad's 1967 A65L. I'm not quite to that stage yet, but I saw an advertisement for the Bob Newby Racing Belt Drive and Clutch for BSA A50 / A65, 500, and 650 cc unit twin.
I have to be honest that part of my interest in this is its simplicity. This would eliminate the loose bearings and oil leakage, etc. I started to add up the cost of all the parts to replace what was there, and it might be almost as much. It looks like I'm going to need a primary chain, chain wheels, and clutch anyway.
Does anyone have any experience with using a primary belt drive and dry clutch? Is cooling really a problem?
Thank you in advance for any input,
