I just finished putting back together the engine out of my XR650L. Since this was the first time attempting this, it took me a few times, but amazingly it started right up and seems to run great. However, when I started to clean up my area, I came across the guide for the timing chain. Like I said, it runs great, but how imperative is it... shoiuld I break the motor back down, or do you think it'll be okay for a couple of weeks...???
