Steven G Posted September 24, 2009 Share Posted September 24, 2009 Hello, I have a Yamaha Jog RR and now I have turned 17, wanted to look into derestriction. I understand I will need to get a new performance exhaust, and take the washer out the variator but is there anything else I will need to do (except jet, clutch springs and rollers)? Many Thanks Link to comment Share on other sites More sharing options...
