I recently bought a 00 YZ426F. It is stock to the best of my knowledge. The problem is it's an absolute bear to start when it is cold. Once its warm or hot it will fire first kick every time. (usually dont even need the hot start) Other than a little bog of the line it runs great. I cleaned the carb and had the valves adjusted. I did the light blue neutral wire mod. I sanded and cleaned the coil mount and contacts and even put in a hotter plug NGK CR7E as a last resort. Still it is a pain to start. It actually seems to try and start better without the choke??? Could this be a jettin issue? I was also going to do the av now or the james now mod. I cant seem to find any instructions on it though. Can anyone help me out with a solution and or the insructions for the mod? thanks in advance..
