My Sport has gotten all spitty and jumpy just off closed throttle where I "cruise," pull away from stops, and out of corners. Very annoying and I remember it doing this when the original TPS played out at 62,000 miles/ 100.000 km.
Using the Caspers Breakout Harness and Triplett DVOM set to Ohms, the resistance jumps all around at those low throttle openings. Time for a replacement!
I've been running a H-D PF4C over ten years (49,000 miles/79.000 km), but those now seems to be non-adjustable so I ordered the CA-CycleWorks PF3C they spec for Ducati. Almost $100US shipped.
We shall see if the "Nasty Hiccup" resolves . . . and how the correct PF3C curve "feels" after all this time with the PF4C.
