My bike was giving me a lot of trouble trying to start it today, it finally started and when I shut it down and tried to restart it, I couldnt get it to start back up. I pulled the valve cover off to check valve clearences and noticed the punch marks had 14 pins in between them. I lined everything back up, the exhaust cam had jumped 1 tooth. I put it all back together and it fired up first kick. Shut it down a couple times and it restarted first kick every time. Im going to replace the cam chain and was wondering if I should replace anything else while its apart?
