Can anyone give me some help on jetting. My brother bought an 05 WR 250 and it runs like crap! We live in Colorado and will ride around 6,000-7,000 ' for now until the snow melts up high. The dealer put a 40 pilot and 158 main with the needle in the 2 position from the bottom so the need is up a bit. The poor thing is running really lean!!! If you go into a corner it dies and if you open it up it had a HUGE bog right around idle. We put a 165 in and dropped the need down and that was still lean. Then we put a 48 pilot and that helps but it is still not good. Dealers are saying they don't know about the 05 yet with the changes. Any help would be good. I told him to get a GG ;)
Thanks
