    Re: Hiccup in power delivery accelerating in 2nd. very troubling.

    Well I'm finally able to start troubleshooting the problem, but now I can't replicate it?

    C'est la vie

    I mean, I'm glad my bike isn't doing the weird thing anymore, but having problems just vanish is kinda spooky and I mistrust it.

    Were you able to actually get out and ride the bike? I thought you had broken ribs?
    If you can't fix it by hitting it with a hammer, it's electrical!

    Yep, back in the saddle, although I'm pretty rusty and a bit sore and weak from being laid up for six weeks.

    Need to build up my stamina again and make sure the bike isn't hiding problems. Hoping to do a bit of a cross-country trek this summer.

    Electrical connections, switches, with issues, can come and go until eventually failing completely..

    Most mechanical (hard parts) issues (say a missing tooth in the gear box), don't come and go, it'll keep "skipping" until the gear gets torn up more or destroys the other gear it mesh's with..

    Re: Hiccup in power delivery accelerating in 2nd. very troubling.

    I'm not pretending that I can puzzle out how it doesn't work, but I'm 90% sure that you were right about the kill switch.

    I never did get to properly troubleshoot, but the bike decided to just up and die halfway to work yesterday with obviously electrical symptoms. Walked over and mucked about with the kill switch today and found a corroded contact that looks deformed. Cleaned it up as best I could and got fizzer home, but I don't terribly trust it yet. I'm going to see if I can find a stiffer spring or bind the thing together somehow so it makes a more reliable connection.

    So, I definitely have a kill switch problem. Hopefully that was also the source of the other problem.

    It almost looked scorched, like there was a spark jumping there. Anyone know offhand what the voltage & current through that switch is?

    No more than 12 volts...

    If you simply soldier the wires together, you can bypass the switch altogether.
    Even if just for testing..

    You can't buy the switch alone, you have to purchase the entire rt hand control...

    As noted earlier, the kill switch is a weak link IF used often- As you've now discovered...

    Overuse doesn't seem to be a requirement for failure.

    Re: Hiccup in power delivery accelerating in 2nd. very troubling.

    The run\kill switch supplies current to the coils of the relays in the starter cut off circuit and to the ignition coils. One starter cut off circuit relay powers the fuel injectors and fuel pump and one starter cut off relay allows the starter circuit operation. Most of the current from the kill switch is used by the ignition coils but it also supplies low current to the 2 relay coils in the starter cut off circuit assembly. The ECU can also tell this kill switch is open because there is no voltages on the negative side of those relays or the the negative side of the ignition coils. This is one way logic can be developed to give error codes from the ECU regarding ignition coil primary winding open conditions.

    There have been DOZENS of threads with exactly the same symptoms and fixes as yours, but I guess that means squat...
    I'm not sure I understand your response. I was just trying to add information. I don't ever use the kill switch and it fried anyway. Maybe my skepticism was coming across as ungrateful? If so that wasn't my intention. Your input is appreciated, I was just voicing that this is a weird problem.

    In any case, I found a knocked-about used unit that I can salvage the switch components out of as spares. I'll let you know if I come up with any solution to make it more resilient. I'd prefer not to disable the switch as a fix. Either way I will be yanking it apart to clean and service every couple oil changes.
