Hey guys and gals! A customer of mine came in with a chattery clutch. It took a LOT of research to finally narrow it down. Then I found this site you guys have here. Thank you for all the great information and ideas. I could not, however, find a step-by-step how to. So, being a firm believer in paying back favors, I created a step-by-step writeup for the M109r Clutch mod. Complete with the newer model updated parts and clutch pin oil-flow modification. So, thanks for all the good advice, enjoy the write-up!
