TPS creep.

[Zanx]

Is there a way of stopping TPS creep? Seems that whenever I get it spot on, it slowly drifts off every couple of hundred miles. Seems like a 2 bolt design would have been better.

It is a 2 bolt design.. yours only has 1..? Would you have a pic?

Being a 2004, if the TPS wasn't replaced then it needs the newer one.

Sure. TPS is new, got a pic.

My apologies I was picturing another bike. It only has 1.

Is it mechanically drifting i.e. you can see the bolt is in a different position relative to the slot in the sensor after a few hundred miles, or electronically drifting as in the volts as found when doing the ISCV reset are different than where you left it?

Presume this is a new TPS came in a little bag with a Triumph label with the part number on it, and you're using TuneECU to set it correctly.
That bolt looks different to any i've got with a TPS.

If its a new TPS. And showing creep signs. I would wonder if your fully close throttle position is changing or floating. All the grime in the throttle linkage and springs can cause that.
This of it as a machine that cycles overtime you power it up. The ecu goes thru its whirly movements verifying home and making the compensations to base line a closed throttle from.
And do you shim the tps to insure it doesn't bind ?
