Major backfire, lost compression- HELP!!!
Hey guys, I'm a newbie and am having a problem. I have a KX 250 and have lost compression. I was riding most of the weekend and late on Sunday I was riding slow and suddenly had a big backfire (or it sounded like one), then the bike bogged and died and I lost almost all compression. It had been running rich (dark plugs) but otherwise great.
I'm guessing I either lost pressure from the rings or worse, the piston blew up. I was gonna rebuild the top end or at least try to, but didnt know if that was the total problem. I'm just hoping I didnt blow the entire motor.....
Any help would be GREAT! :bang:
