All I can say is WOW!!! Bike is amazing, best I have ever riden. I finally rec'd my carb from ZipTY and Rekluse Pro clutch came the same day, got everything together. I need to do some minor adjusting. On the first ride, took it easy for first and then let her rip. Its absolutly a rocket, very smooth, I could loft the front wheel anytime I wanted. I just loved the feel of the whole bike. Here's what I did to it, THANKS to all of you off Thumpertalk. 07 YZ450F White ZipTy Carb Mod 1/4 Throttle Mod(Love this mod) Dubach Carbon Fiber Exhaust Rekuse Pro clutch & cover W/C Stuff mostly for looks W/C Skid Plate W/C starting device Enzo Suspension Mods Rental O-Chain & Sprokets Step Seat Black Excel Rims Custom Graphics & numbers Michelin MS3 front, MH3 rear Moose foot pegs I race the +50 Expert class and I think I have the perfect bike for my style of riding. The carb mod is great, no bog or hesitation from 0 to wide open, tried a 3rd gear start and scared the crap out of me, it was fast. The Rekluse will take a bit to get use to, I like it, it needs a bit of fine tuning. 1/4 throttle mod is great, it's no effort to twist it, nice mod and easy to do. Dubach Exhaust seems good, haven't tried the stock so I can't really. compare. So far I am really please with the set up, just need some track time now!! Thanks again to everyone a Thumptalk for all the advise.
