About the TM i really like it! i thought it brought a big difference out of my bull. ive hit 85 mph! About the jets, yes i tuned the carb very well i think. as far as i know i guess. the bike seems more powerful and does not pop at all it idles good and everything. I cant remember what the jets are. although i posted them on the yahoo groups as 200 main 30 pilot P6 needle and stock needle at third groove(middle i think). Im thinking about going straight pipe so ill have to re jet accordingly and ill let you know what i have on it for sure.
