K 75 weirdness
Intermittent gremlins are such a bitch. Sixth sense is guessing an
engine electric issue. At the point I do NOT know where to go next ! Maybe it's time to buy a new GS and be done with it. LOL Gary ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~ Two months ago, I experienced some intermittent weirdness on my K 75. Engine would NOT rev over 3K without stumbling/stalling. Limped into a service plaza, dumped the fuel suspecting contaminated gas,refilled with fresh petrol, NO change. Out of desperation, I re-inserted the ECU brain plug, BINGO, fired up, away we go into the sunset. R&R the fuel filter upon return to the house,new spark plugs,fuel pump,coil connections inspection, ignition & kill switches seem OK. Ran perfect, over 2800 miles __________ till this afternoon. :-( ECU was un-clipped and clipped back in for the second time, ____ ball game back on. Why is a mystery as it's NOT loose,corroded,etc. In the garage, damn thing purrs like a kitten,unable to produce any weirdness, go figure. questions: It is possible the TPS is sending a funky signal to the ECU to cut-off to avoid over driving the engine ? How long should a TPS last ? Should I suspect a Halls Effect Sensor slowly going south ? How long/mileage should a HES last ? I seem to remember someone posting the electrical values of the TPS a couple years back. Could you please post them again. Wish I had a spare ECU to swap but they rarely fail. NO idea on how to test one anyway. 1994 K 75 standard 253,000 miles (data point) order of flailing on the slate for Monday #1 re-check the coil connections #2 ignition wires ohm readings #3 visual & electrical inspection of the TPS #4 Jeff Dunkle's HES hairdryer test #5 ICU don't you use some kind of anti thermal paste on the backside snobum ? Anything else I'm missing here ? THANX

My TPS reads 0.36 volts at idle smoothly going up to around 4.75 volts at full throttle, measured between the end pins, I know its different bike but I hope it will give some indication.
