I'm hoping there might be someone with a good suggestion for my problem. I have a 2000 KDX 220R. I just put a new piston in it because the last one, the stock piston "gernaded" - with what I thought was little damage.
[side note: when it blew up on me, it stalled the bike immediately, but since I was in the middle of nowhere, I had no choice but to try and kick it over, so I did. It started and I drove it 5 miles home (very delicately). It started when I got it home too)
Okay, with the other options of 1)replacing the motor or 2) tearing this one completely down I decided to {based on a good compression test} 3) replace the piston and see what would happen. I took off the head and cleaned out the cylinder. Re-honed it and put the new piston back in. Game day came and I kicked it over. Boom! It started first try and I was off. Test drove it up the road where I stopped by a neighbors. Tried to kick it over when I left and it wouldn't start.
I got it home and found that the spark plug had gone bad. (There was no spark when I grounded it on the motor) so I replaced it, the new one sparked, so I thought this was a dead ringer. But now, it still won't start. I know there's spark, and I'm assuming there's still good compression, the plug looks wet and smells of gas, so what else can it be? Weird timing? Did a piece of the piston that I didn't get cleared out screw something up? Not re-assemble something correctly?
Thanks in advance for any suggestions you might have.
