Awesome bikes. Mines an 06'. I've put a PowerNow in the intake and re-jetted with JD jetting. Other than that I change the oil regularly. You have to realize that it's a 250 and ride it as such. However everyone I ride with that has a bigger bike (even Orange ones) loves it. Be ready to swap sprockets depending on where you ride. Stock 13/50 for woods, and 14/50 or 13/48 for the desert. I've also run 15/48 on a run from Mojave, CA to Primm, NV. 50 to 60 mpg, and I've even ridden it to work (15 miles on I-15). It's a keeper.
