I wouldn't recommend jumping at the starter. check your syl. switch to see if the fire is going threw and the switch on your handle bars .

possibly carb out of adjustment

check for a jammed clutch cable not letting the clutch engage

Had the same problem on my 2003 years ago, and corrected the issue by replacing the wires in the headlight shroud and the connection plug. (Wires were somewhat fried for some reason, and were reducing voltage at the terminals, causing a high current condition.

lwr end noise is always bad. if bike has less than 100k km the crankshaft should be ok. very likely there is something in the primary wrong, like the chain or chain tensioner, or clutch hub. remove primary cover and check.

150-165 foot pounds with two LINES of Loctite 271 red in the threads of the nut. Yeah, it's tight and you will need a primary locking bar to lock the primary so that the engine will not turn over while applying torque to the nut. A primary locking bar is a piece of rectangular metal stock cut the precise length to fit into the primary chain teeth on engine sprocket and the outer clutch shell in order to prevent the spocket from turning. Good Luck, Steve
