Information relating to the Matchless G80 or AJS Model 18 500cc Heavyweight.
I have been doing some reading on other forums etc on these mods and some quarters believe that they cause the big end to give out. I would be grateful if someone can shed some knowledgeable light on this specific aspect.
Hm.. I could see that, especially on the drive side. ball bearings I don't think are the best choice for such an application, rollers would have been a lot better. I just pulled the set of RLS8's out of the drive side of mine and with only 4400 miles on the bike, the bearings were already showing a lot more wear then they should have.
