I finally went to a track near me and it was soo fun. I had a blast. Then I fouled my plug after a few races. Its been happening often too and NO im not babying it. Im using Yamalube and reg gas and a ratio of 32:1. A br9es plug and i have the air filter clean. It has a fmf fatty and powercore 2 and is jetted. Any ideas. Heres a few shots of the track anyway!

I wouldn't say ,"period".
Could also be a worn right crank seal sucking some oil or bad seal letting coolant in.
Maybe even worn rings.

The easiest way to check your jetting is to adjust the clip on the the jet needle (no tools required). Since you're fouling plugs, I would try moving the clip up one notch (so the needle sits lower, giving a leaner mixture) and then see how the bike performs. If it's better, then you may need a smaller main jet.
