what midget said on the tps reset for your year XB. riding in learn mode is as follows: with gear on and ready to ride....and red run switch to off....turn on ignition switch. let gauges sweep, then red run switch to on. let CEL light cycle thru then turn off. start bike and let idle approx. 1 minute till a bit of warmth in motor, and now ride for distance of approx. 20 miles. during this ride cycle avoid prolonged idling, no full throttle riding, avoid long hard up-hill pulls and jack-rabbit starts, and no trips to redline. in other words ride normally but a bit tenderly with the throttle inputs.thanks for the fast reply, the filter, plugs, no problem, tps reset do'able , please explain "ride in learn mode", thanks
