Left cylinder not firing

[jaredvh]

It appears the left cylinder isn't even getting hot at low RPM's. I idled my shee for about 10 mins with brand new plugs.. the left side came out white and the plug was just warm. The right side plug was normal. And it was hot. I pulled the plugs and checked spark and its sparking on both sides.

 

When I ride it it has no power through 1st and 2nd but once I hit 3rd it takes off hard.

Forgot to mention, but its probably obvious.. The exhaust coming out of the right side is hot where as the left is cool.

 

I pulled the end cap off of both spark arrestors (stock pipes). The left side was soaked inside with carbon buildup. The right side was dry with the same buildup.

i had similiar problems and it was a bad stator, swap it out with a known good one..and see if that changes anything

Well.. I just pulled the stator cover off and there was some water underneath.. Should I order a new rubber seal and a new stator as well? What should I be looking for when buying a stator?

The other day mine did the same thing. I noticed the left side did appearing to be "running" in the lower rpm's. Then it got to where it wouldn't idle at all. Mine turned out to be bad reeds, it wasn't making enough compression at the lower rpm's I guess.

Compression on my engine while cold is 95 (left) and 105 (right).
