After a long business trip, I decided to take the day off and go out to El Mirage. First time out there with my 09 X and I took my GPS and decided to do a top speed run. I have the following upgrades: IMS 3.2 tank (half full for the run) Precision Concepts Stage 3 kit (jetting, 08 R Cam, air box mod) Precision Concepts air pump block off kit ProCircuit JCR full exhaust system (spark arrestor removed, competition tip used) 14/48 gearing (SunStar steel sprockets, Renthal non-o ring chain) Maxxis Desert Tires (120/100/18 in the rear, standard size up front, 15 PSI each) With it being a windless day, I was able to consistently pull off 101 mph. Considering I am 6'5 and weigh 225, I was pleasantly surprised with my results! This is still the best and now the fastest bike I have ever owned!
