will an xc 500 pull 58 gram weights??? if so what primary spring do we need to use to get it to run... Just looking for a cheap way out on rebuilding this clutch. Already have a set of 58 gram weights.... stock was 54... I'm assuming the 4 gram difference isnt going to make THAT much of a difference as it is for a beginning rider.... What primary spring would you suggest to make it run good with those 58 gram weights???
