I just did a couple mods to my 01 WR. I went yz timing and pulled the airbox lid off. It runs pretty good overall but Im having some trouble down low. It seems to not want to come back down to idle. Im not sure if this makes sense. After being full throttle it wont come back down to idle. It sounds like my idle is way to high, but if I sit for a minute it comes down. I am also having some backfiring on deceleration. It running like a bat out of hell on the top. Its only a deceleration problem. Right now Im runnin; 170 main 45 pilot EJP needle #4 100 PAJ fuel screw any where from 1/4 turn out to 2 turns out, neither way seemed to fix my prob. I have a 42 pilot and an EKP needle around, should I try either of these? I was also thinkin maybe my float height is off, how do I check this?
