Renthal sprockets, one up out front one down in rear helped the boy get used to the power band, now I'll probably go back to 13 in front and up a couple in back. Put a DEP Pipe, FMF torque reeds, jets, and now the bike gets it pretty good. Its always something that's needing fixing or adjusting on that lil thing. Got new EBC Clutch and springs and Hot-Rods crankshaft assy ready to go in when needed. Still got stock muffler, thinking about going Pro Circuit Shorty, can't find a DEP to go with pipe, do they make em? They're European or something. Got the pipe on eBay.
