i am going to have the valves adjusted and have them check out the cam chain and gears while its a aprt. bike has 15k on it and it starting to make a little noise. dealer mechanic is top notch and is aware of all these issues. while its in there and a part i was thinking of heavier clutch springs. good idea or no? also i cannot find any part numbers or place to get them from. if its a good idea where could i get them and what should i get. thanks
