So not even a kick over for a sec. Even with a shot of start fluid. Or giving it some gas.

You can buy a curtis sparks tps bypass or make one your self. By taking the wires going from the harness to the throttle and cutting it on the throttle side with room to splice them together.

      I have a 1995 Yamaha 350 big bear and I am having trouble starting it. You can hear the solenoid click but starter motor won't engage. Should I be looking at the starter motor or solenoid?  Any suggestions are appreciated.

      If we had a dollar for every time the question “Which is really faster, the 700 or the 450?” shows up in our inbox, mailbox, or voicemail, we’d be putting this magazine together from a bungalow on a barely inhabited tropical isle named Quadhama.

      I am a new member and was hoping i could get some good info on why my 2002 yamaha blaster atv will not run. the ignition light will not stay on when i try to start it. i put new plugs, cleaned gas. when i pulled it with my pick up with someone on it , it would start and run, now it will not even start by pulling it now. any one out there with some good advice?
