What are your thoughts? I would like to be somewhere in the ballpark of appropriate jetting now that the motor for my 01 KX is done. I went with a v-force reed valve, FMF Fatty pipe, Turbine Core silencer, and 310 big bore. Gorr suggested going one jet richer on the main, and one jet leaner on the pilot (from stock jetting), however, I didn't tell him of the other additions I made to the bike, such as the reed valve and pipe. How much will this affect the jetting? The bike ran really rich from the factory. I will also be running a BPR7ES plug. Mostly ride woods, with some hill climbing, so it will see full throttle often enough to leave the main a little rich.
