RPMs drop to Zero!

[DCRocket]

Well, some of you may remember I replaced the TPS not so long ago and fixed my low idle/stall problem. This weekend I took a trip from Chicago to Columbus, OH to hang out and ride with a few friends - bike ran flawlessly. Got up early yesterday to return, ran about 10 miles to first stop light, downshifted, clutch in and revs dropped to zero, engine dead. (Definitely NOT operator error.) Fired her up and bike ran flawlessly all the way home and again today to work no problems.

WHY???

Can the ECU have a brainfart? just stop communicating with the TPS and Idle Speed Controller? What else could possibly cause this one off issue. I want to blow it off (really!) but my mind won't let it go, so looking for some thoughts, reasons, advice --

Thanks,

ain't got a clue, but give Wayne Tripp a call would be my advice.

Idle speed too low when hot? is the fuel filter clean ( clean fuel lines?)

Yeah, but what else happened when the engine stopped? Instrument lights? Headlights? Crook (intermittent) ignition switch soldered connection did that to me when it cracked.....

did the same to me at 752 miles from new fired right up, now got 30,000 plus miles never did it again.

..sometimes mine will stall without warning..only a few though..the last one, I was making a u-turn on a 4 lane highway, one side just recently paved, but not the other..I was easing up onto the newly paved road (bump) in the middle of the u-turn when it did it..****er..my mate behind me went wide and around..a quick hit of the start button kept her going forward..****er..

Mine has done that as well (shut off) at very infrequent times. I attribute it to the great Brit electronics (ghost of Lucas) installed within it and have my expectations adjusted accordingly :mrgreen:

Two things I would consider are, sudden air temp change and low voltage sensor calibration.

Ya mean he Farted into the electrics & that was the end of that!!! :exit:

Yes Bones or maybe the methane injection system was overloaded.:spitcoffee:
