Description

Details

The Sparks Racing TPS Bypass Plug is a very simple fix for a seemingly complex problem within the 2004-2011 YFZ450 ignition system. The YFZ ignition actually has two timing curves, a partial throttle curve and a full throttle curve. In stock form, the YFZ has a very noticeable hesitation or stumble when accelerating and this is due to the poor transition between the partial and full throttle timing curves. The Sparks Racing Throttle Position Sensor (TPS) Bypass plug switches the ignition to the full throttle curve which eliminates the hesitation and offers a better overall timing curve. This Bypass plug works on stock and aftermarket CDI boxes.

****Please note: The 2012- YFZ450 uses a different ignition system which is not compatible with the TPS Bypass Plug.
