is ur pickup coil rubbing the flywheel? r you sure its comeing from the engine and not the chain roller? i had a worn out roller and i thought i fucked up my tranny cuz i heard a weird grinding noise but it was just the chain sliding off the roller

pretty sure you have a bad bearing somewhere. get a grip on the grab bar, and shove it side to side, and watch for play in the swing-arm, lift the front wheels off the ground and check for bearing play, check your chain slack after, and the chain rollers. do you notice any pulling, or play while riding?

Check ALL of your chain rollers including the one that goes around the swingarm pivot. They are notoriuos for wearing through and the chain cutting into the swingarm, replace it with a chain slider.

Check chain rollers and chain tension while sitting on it. Too tight of a chain will make noise on bumps and when coasting as the engine noise is lower allowing u to hear it slowly wear your rollers/sprokets.
