Do we know yet wether the WR450 can be timed like a YZ? I went from a WR400 to a new 450 and I am not impressed with the power. It is broad and has good torque but not much top end charge. Throttle stop was cut, baffle removed and air box snorkle removed, still seems reluctant to pull the front wheel in 3rd gear and above. I think my old 400 would out run it...no flywheel key problems yet!
