Last weekend we were at Turkey bay (LBL KENTUCKY)beautiful area and nice riding. This yz rips on the track, but we had to push and burn the clutch up the hills. It has 2 extra teeth on rear sprocket, v-force reeds,& SST FMF pipe on it. But we need more on the bottom end to keep from bogging up these hills. Thought about rising the compression ratio. What are my alternatives, What's the best bang for the buck? What are your thoughts and input? THANK-YOU MY SON WOULD LOVE YOUR INPUT
