So went out for a ride the other day on my bike and it was going great, then once I had been on it for about 20 minutes the rpms started jumping up and down. I kept on driving thinking that it might've just been something in the gas that it needed to burn off, but unfortunately it started doing it again a few minutes later. The clutch on the bike is definitely on its way out (when I changed the oil there was fragments in the oil of clutch) so i'm not sure if this is a issue with the clutch. But what the bike does is you can shift it, but it has a serious loss of power. Not just this, but the tachometer shows nothing. And when the bike does perk back up, the tach will show the proper RPM's. I tried searching for videos of this but I haven't had any luck. I'm gonna call the local bike shop and see if they have any idea as well, but figured I would ask on here to see if anyone has had or heard of this issue before. I plan on changing the cam belts and clutch this weekend. Any help or advice is greatly appreciated!
