I have a Traxter Max 500 with auto shift. Problem is bike won't shift out of first gear. When you hit the shift button selonoid makes noise and bike feels to disengage to go to the next gear but remains in first. If you are in full auto mode the speed sensor is doing it's job and attempts to shift the bike just as you would manually but again won't come out of first. Has anybody had this issue and what was your resolution?
