I picked this bike up in June and love it except for its lack of low end power to pull me in tight, technical woods. I'm 5' 11" and weigh 245 lbs. At first I was going to get a larger rear sprocket but after reading posts in TT, I decided to just go down one tooth on the front. This approach also saved me a ton of money because if I changed the rear, I would have needed a new chain to match it. Changing the front sprocket cost me $18 (Sunstar) and was the best mod on the bike to date. I love second gear now. I can now use the throttle to get me out of trouble and maintain much better control of the bike. I used to have to either run in first (engine braking was more disruptive than having the available power ) or feather the clutch like crazy in second. The bike's character has changed quite a bit and for $18, was much better than any of the free mods I have done. I'll get another season out of it before I go to a bigger bike. Thanks for all the posts that led me to this decision. TT rules!
