General Discussion / Re: How Reliable are Kymco Fuel Injected Scooters
« on: September 21, 2011, 03:39:31 PM »
Hello people,
I joined this board to hopefully give everyone a suggestion about this idle problem that seems to pop up. Without boring you with the details, I traced the problem back to the throttle position sensor (TPS). It seems dirt and grime can carbonize inside this sensor and affect the idle. Most people keep seeing their bike "speed up", when in reality what is happening is the ECU is trying to keep the motor from stalling. If the ECU doesn't receive a valid signal(or an incorrect one) from the TPS, then it simply stalls.
An almost no-cost fix is to clean the hell out of the TPS with electrical contact cleaner while working the sensor through its full range of movement. You only have to remove the seat & storage box for access. It sits on side of the throttle body.
Good luck.
