I run a FMF Fatty with a Pro-Circuit silencer and I had to lean out my jetting in order to not foul as many plugs.. My carb is a mikuni and instead of the 370 main jet I run a 340. Kawasaki runs Keihin carbs right?

I installed a different non stock pipe/silencer in my bike and it created a rich condition.

With Boyeson Pro Series reeds, SST and Turbine Core we went down from a 38 to a 35, it still runs slightly rich, with VP C12 and 32:1 we occasionally run a 32 main. The KX 100 is notoriously spoogy.
