This TPS bypass plug will give you a small boost in power on a modded bike with a higher compression piston. Also great if you don't want to fool with TPS adjustments or suspect yours is acting up.
 
Just unplug your TPS from the carb and plug this into the harness ans that's it!
 
What does it do? It tells your CDI that your throttle is 100% open at all times and changes the timing curve.
