Help! I have a 01 WR 426. It had real good power out of the box after I cut the throttle stop, took out the baffle, and the air box top off. I did want more snap though. While I was having the valves checked I had the dealer advance the ehxaust cam 1 tooth. The bike now is a gutless wonder. It has no tourque, no hit, and won't rev out. I have not jetted it yet because I am still waiting for the parts to come in. I ordered a YZ needle, 180 main, 50 pilot, and 100 air. I am currently running a Uni filter also. Does the bike run like a dog until the jetting is done? Have I made a mistake? I also disconected the "grey wire". I was just shocked the bike runs slower. Actually not just slower, its a dog! Please help!
