My bike keeps eating flywheel keys. I just took the motor completely apart to make sure the crank was all tight, it is just like brand new. so we put in a new woodruff key and torqued everything back down. I also put a top end in because I already had it apart and my compression was a bit low anyways. Today I went to the pit and maybe 20 minutes into breaking the bike in, it starts sputtering and knocking and then stalls out. Took off the flywheel cover and the nut had backed off so much that it spun off by hand and of course the flywheel chewed up the key.
Has anyone else had this problem? and how do I go about fixing this? Tomorrow im going to grab another key and try to locktite the nut on. any other suggestions??
Thanks
