Hey guys, I am just wondering......is the vortex CDI the only option to fix my stutter? I have spent 9 months jetting in every way possible and the stutter is still there. James Dean posted some info about WR ignition problems at steady throttle and it certainly looks like a CDI problem that I am having. BTW the bike is an 07 and has done this since the day I bought it, TPS unplugged or not, the stutter is there. Jetting can minimize the problem, but never make it dissapear. I need to know if a new WR CDI is a reasonable option, or maybe a YZ unit...or the most costly option - the Vortex ignition. What do you guys think?
