Hello great site, just purchased a 01-wr426 and alot of my mods on the bike came from here. Now if anyone can help? I ride trail in Alberta Canada between 2000-6000'. The bike has the BK mod, FMF Q-pipe, stock head pipe, wr timed, yz throttle stop, air box lid removed,blue wire cut, 168 mj, 45 pj, 3 turns on the fs, DRQ pos 3. Power is good all round but I'm running lean I believe as it pops decelerating and at steady higher throttle settings. Also at idle it does not want to come down for a while.
