Well, after experiencing different symptoms with my 1972 XLCH, such as hard starting, flooding, popping out the carb, even with a new Mikuni, new battery, new Dynatek ignition, I did a compression check to find both cylinders reading 30 psi when warmed up, 60 when cold. I've adjusted the pushrods so thats not the culprit. The PO had the top end redone, so that is suspect. It starts fine when cold, hard as hell when warm.
Strange thing is, when it starts up, she runs fast and strong, with no smoking, although there is some oil spraying out the breather. How can this be?? I would imagine if I had compression that low, she wouldnt even start, much less run and idle good. It even takes all my weight to kick her over.
I've tried two different comp testers with the same result. I checked the cam timing and it looked fine:
Also, here's vid of me kicking her after I did the comp test.
This is driving me nuts. Any ideas??
