Is there a good source for a service manual for the 650 V-twin. I have a 2002 and would like to have a service manual detailing things like belt adjustment. I have only 120 hours on mine, gentle riding and the belt was swealing at take off. $68 dollars later I have a 'shim' inserted by dealer and for the moment the sweal is silent. Someone else had asked how long these belts should last? I have the same question. I like the 650's power etc. but next time no belts!
