Since installing an FMF Gnarly, TC II silencer, and Boyesen Power Reeds, my bike runs as rich as German chocolate cake! I have dropped my main jet to a 140, changed to a 40:1 ratio (Yamalube), and moved the needle clip to the #1 position. Still blows black spooge on my rear fender and struggles from mid to top end. How low has anyone gone on the main jet? I feel that a 140 is already low. Riding in Nashville, not sure on the base elevation. 02 KDX 220 stock engine except for the items listed above.
