I just want to say thanks for all the posted info. I was so close to selling my 02 426 and going back to 2 strokes that I had already bartered a deal for an 04 CR 250. I stumbled upon this message board and found the hot cam mod helped with the starting issue. On Monday I ordered the intake/exhaust Hot Cams, shims and compression plug. They arrived on Thursday and the bike was running that night. I was so tired of finding a rock to stand on so I could throw all my weight onto the starter and the snickering/finger pointing during races when this happened. Now I have new hope for the bike. Today will be the virgin ride with the new cams. I feel like a 5 year old on Xmas morning! Now if I can just solve the plug fouling problem I'll be set. I've ordered the JD Jetting kit and will put it in after I feel comfortable that the cam mod is performing well. Thanks again for all the info!
