First let me say I really enjoy this forum. I have gotten these ideas from here and other places mentioned here, so thanks. I race harescrambles on a CRF450R modified for the trails. What do you guys think about this project? The bike is planned to be ridden in the Vegas to Reno race in 2008. The main goal is to safely finish the race. Here is what I have headed my way for the bike. What are your thoughts? What would you do different and why? 2007 XR650R Uncorked. Protaper Bars. Scotts stabilizer mounted up top. Shark fin. UNI Filter. Utah skid plate. T-4 Pro Circuit full exhaust. Sidewinder Tri sprocket 48 tooth. Sidewinder Tri Moly CS sprocket 15 tooth. Sidewinder fancy o-ring chain in 10,000 lbs 520. Jetting will be 172, 175, or 180 main with 68s or 70s pilot. Clarke tank (near) 4 gallons. I haven't decided on exactly which one. Ricky stator 200 watt setup. Race Tech lights. Factory Connection suspension revalving and respring. Bridgstone ED77 front and back. Bridgestone ultra heavy duty tubes. These tires are a starting place. We will test in various conditions to see how they work. I am not planning to do anything else to the motor. I think it will be plenty just jetting properly and letting it breathe. I would like a speedometer, any suggestions. Maybe Maier hand guards. I do not have the stator, lights or tank ordered yet.
