First time at a track...

[2001Rm125]

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!

If you are fouling plugs, the jetting isn't right. Period.

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.

True.. but I'd start with jetting.. Just me.

Well i can say i kno quite a bit right now im 15 but i dont know much about jetting. The guy before me told me he jetted it for the pipe should i jet again>?

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.
