coryv4 Posted August 21, 2011 Report Share Posted August 21, 2011 i can hear a kind of grinding sound coming from the left side of the engine when i coast. any clue what that could be? it gets louder when going over slight bumps. 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 Quote Link to comment Share on other sites More sharing options...
AKheathen Posted August 21, 2011 Report Share Posted August 21, 2011 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?

bansheesandrider Posted August 21, 2011 Report Share Posted August 21, 2011 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. Quote Link to comment Share on other sites More sharing options...
boise_banshee Posted August 21, 2011 Report Share Posted August 21, 2011 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.
