NATH Posted March 26, 2010 I have used the search and read many posts about the constant light throttle stutter common to many wrf"s. If this is an inherent problem with advance map of the yamaha CDI, would it be eliminated by fitting an aftermarket CDI? maybe a vortex X10 for example... I don't want to shell out for one only to find it does'nt fix the problem.. (Runs smoothly with TPS unplugged but down on power.) Share this post Link to post Share on other sites
William1 My Rides (2) Posted March 26, 2010 Yes, one or two of the maps on the vortex resolves it. Share this post Link to post Share on other sites
