Never seen the problem on any of my bikes. But troubleshooting I've read suggests it's probably pulling in trans oil through that seal causing the problem?? Worth looking into at the least. Sounds like you have safely eliminated anything real obvious.

Chase,

Sound like it's sucking trans oil for a blown\weak wet side crank seal.

Go take the spark plug out & see if it smells like oil.

It never has when I've had it out. I'll get some crank seals ordered up, they are cheap enough and it won't hurt to replace them.

Update, bought a compression tester yesterday and I think I may have found the issue...



I did check my gauge using my air compressor and I'm confident it's reading accurately. And yes, I did hold the throttle open when doing the compression test. Next step is to measure the cylinder to see if it's out of round, then get some parts ordered up.

Bringing this one back from the dead. I have been working on getting this little bike going again slowly, my boy really wants to ride it. I replaced the piston and had the cylinder lightly honed, and it fired right up and was running awesome in the shop. Trying to ride it produced the same old result, it sounded like it was loading up (not smoking any more than usual this time) and wouldn't stay running. I had a parts bike that I robbed all the electrical parts off of, thinking it may be a problem with the stator or the coil? Still need to check those crank seals also.
