I have a 2001 426 and agree I just bought it,tried to ride it for the first time last weekend and could not cold start it. Luckily I was near a hill and roll started it. after that it was firing fine warm.I was nervous because i felt if I couldnt start it cold I was done.i read your forum and did the resistor swap yesterday,and cold started it on the first kick with regular shoes!!!!I have also considered this cam upgrade for simplifying the gadgets to start the bike and it looks like HOTCAMS sells a cam with decomp and performance improvement for under $200.00 why not use this? just curious,this forum is great and I really love the big block feel of my 426 over past kx250 bikes I had forever.Thanks for listening Im ready for the beating LOL.
