Hi all I've searched this board for a while now to try to find an answer to this midrange sputter/missing whatever you want to call it problem. Has anyone come up with a resolution and if so could you steer me to the right string? My problem is at freeway speeds (55-65 mph), trailing/neutral throttle probably 1/8-1/2 range. Doesn't do it over 70 or below 50. Has done it since bone stock and every other jetting combo I have tried so far. The bike runs strong everywhere else and bangs the rev limiter in top gear. I don't notice it offroad because I'm never at a steady throttle. Current setup: 01 WR426, YZ Timed, no lid, Cut gray wire, Dr. D pipe, 168 MJ, 200 MAJ, EJP #1 thru #5 #4, 45 PJ, 75 PAJ, lot's of pulled hair and pissed off family cause I'm in the garage so much. I'm even ready for a lashing from Taffy!
