Hey guys I know there are lot of posts already on this question but I figured I would ask because of my individual circumstance. My bike has 60 hrs over half are from fairly easy trail riding the rest are from about a half dozen times I have raced the bike. Is it time to replace the cam chain if I am a little premature on replacement I wouldn't mind waiting as I have have other projects how ever obviously I want to avoid bad things from happening. It will probably have closer to 100 hrs next time I have chance. Is ok to wait until it has 90-100 hrs. The bike has not had the day lights hammered out of it. Thanks in advance.
