Chain noise
I replaced the Chain and both sprockets and still no difference.... I think the issue is friends is that the rear axle and where the rear swing arm are clamped together to hold it once you tighten the chain are wore out and it is letting the axle spin back forwards therefore the chain will not stay tight enough. That that is my diagnosis anyways. Simple solution just get another rubber pad and double it up on top of the other one and it will raise your chain up away from everything and also keep it a little tighter at the same time, problems solved.... 😉
