I have an 03 WR250, with the throttle stop cut, YZ jetting, Air bok opend up, and an FMF Q pipe. (No I did not remove the Grey Wire) I am happy with the power, but it is too loud for the area I ride in. I am thinking about getting an 05 WR450, or possibly a CRF 450x. I am curious to know if anyone had done the throttle stop mod and or the Grey wire mod, while leaving the stock baffle in the exhaust. I am trying to figure out how powerful/fast the bike can be while still metting the 82db noise level. Thanks.
