I'm seeking advice on changes to my jetting. Two months ago, I purchased a used (only 55 miles) 2002 WR 426. I have done the following mods: removed airbox, removed baffle, cut grey wire, and shortened throttle stop. I ride in East Tennessee at altitudes ranging from 400 ft to 1100 ft. I am currently not pleased with the bike's performance. It does not have a crisp throttle response, especially bogging at low end. I also get some popping when coasting downhill in gear. I don't know all the numbers yet, but all my jetting is currently stock. I run premium gas, and keep my stock airfilter clean. I haven't checked my spark plug yet. I have done a lot of research on jetting here on TT, but most of what I have seen refers to higher altitudes. I am hoping to hear from LarryCO or Taffy, as it appears that they are somewhat of jetting legends around this place. What should I change to? I really appreciate the help!
