YZ125 Starting Issues

Recommended Posts

Hi All. Having an issue with my son's new to us '02 125. Recently finished rebuilding the entire bike. New everything, not by design, but out of necessity. So many issues.

Bike fired up on second kick after rebuild, and we broke in engine as per the manual.

First time we go to the track, my son, brand new to dirtbiking but with lots of time on a quad, warmed the bike up, took off for his first lap, and had to push the bike back to the truck. Turned out he left the choke on. We haven't been able to get the bike running since. I've checked spark, changed the plug twice, drained the fuel and replaced, bought a compression tester and checked compression, which is at 150, and the air filter clean spotless.

With no throttle on, it sounds like it wants to fire on about every 5-6 kick. Trying to start with the throttle on even just a little sounds like its totally bogging. I've tried starting on multiple days, same results each time.

Any suggestions?
