I thought I had serious problems on the ride home this afternoon.... I got about a 2 miles from the house and heard an awful noise...I'm like ! So I continue a bit bike seems to be running fine and smooth.... ... I' continue a little further and I think this kinda sounds like its coming from the engine.. The more I listen the more my mind is trying to diagnose the issue... Sounds like a chain making contact... I'm thinking great, cam chain guides or something... I go on and make it home and as soon as I stop the noise stops... Motor sounds good.... I crack the throttle and the engine still sounds great.... So I ride around the yard and the noise comes back.......stop and it quit... O.k is something other than the engine......... He's what I found...........Broken drive chain guard I'll take that over anything to do with the cam chain....
