...TPS was used in conjunction with 2/3 gear sensor to retard timing for noise emissions purposes.
I have a feeling this one may actually apply. I had adjusted my idle sometimes a few times a day with CVs when it went from cold to hot during a ride. I doubt my TPS was right from a few hundred miles into ownership and I never suffered any of the possible problems listed above that could be potential results.
Who knows? I'm pretty jetting sensitive, I have been spending too much time jetting perfectly good bikes with JD kits and hours of test & tune to get them right. The hit I'm describing is from 1/16' throttle to a hair above it. Not unmanagable, just noticable power increase that stays that curve thru the midrange.
