Are you allowing your bike to idle for 600 seconds, 10 minutes, NO THROTTLE INPUT, then riding it for a while under 3,500 rpm to allow your ecm to "adapt"?

And are you doing the TPS reset with the engine HOT?

The TPS reset is a "zero" calibration. Think of a volume knob. Your throttle is the knob, and the computer needs to know where "off" is. That position is the baseline for EVERY SINGLE CALCULATION that the EFI performs while the engine is running. It has to know the throttle position (what "volume" setting is it on?) so it can set fuel delivery, spark advance, and use it as a reference for O2 readings, etc.

Your bike runs when it's hot. Therefore, you need to "zero" that volume knob when the bike (and the throttle plate) is hot.

If you have to re-do it frequently...you have other issues. Changed exhaust and not the computer? Intake gasket leak? Timing slipped? Have you pulled trouble codes? Checked your throttle cables? Cleaned your air filter?

What is going you think you need to reset the TPS? It automagically self calibrates periodically.

Froggy automagically is probably my favorite word...

Also when you are reading the TPS values in diag mode you need to have the kill switch set to RUN...
