[QUOTE="longtime coming, post: 1393411, member: 67999"] Warm it up good. Then just take it for a short ride (15 minutes or so). Ride it on hard ground, not deep sand or dirt. Work it hard to 1/2 throttle, vary the throttle position constantly. Doing short figure 8's would be perfect (1st, 2nd, 3rd gear up and down). Let it cool, check for leaks, check the headbolts and anything else you loosened. Then just ride it. The engine usually lets you know how it feels. Don't make it struggle, but don't coast around either. It doesn't take very long to break in the rings. And if you're too easy on it, they don't seal as well as if you ride it with authority, but only to about 1/2 throttle for the first 20 minutes or so. After about an hour or less, it should take whatever you want to give it. If the jetting was good when you tore it down, it should be good when it's back together. But watch the plug and make sure it is blowing blue smoke while it is warming up. works for me. [/QUOTE]
