Re: what did you do to your motor bike today?
On one of my bikes, my manual clutch was slipping. I adjusted the flower nut but didn't work for me. I removed the centrifugal clutch to get to the manual clutch. I removed all 15 pucks and used fresh cyanocralate glue to glue sand paper to each puck. CA glue is super glue but don't use the garbage fromr retail stores. Get the good stuff from a local radio control model airplane hobby shop. Use either thin or medium CA. Caution-thin CA glue cures very fast and its cure is exothermic meaning it emits a lot of heat capable of causing a 2nd or 3rd degree burn which sucks if it accidentally glues your fingers together...great for sealing and cauterizing a wound that may require a couple of stitches though.
Works great and should last a long time since I VERY RARELY disengage my manual clutch when I'm riding...my centrifugal clutch does all the work automatically for me when I STOP.
