My bike is in with JJ (recommended bike builder in Sgp - PM me for more info). I asked him - amoungst other things - to put a new set of clutch disks in. He showed me the clutch basket today - there is slop between the alloy basket and steel drive gear/back plate. The two are held together with four rivets - I think the rivets are 'wearing' under my continual clutch abuse. He's recommending a new clutch basket but I'd rather just have the basket/steel gear re-riveted. Has anyone done this before?
Take a hammer and pound the rivets back to flush.
