    1100 GS Neutral Light,not working.

    I just bought a 1997 R1100 GS,the first day every thing was fine.Turn the key to on,the green neutral came on then start it up.Now when I turn it on the green neutral light does not come on and it will not start unless you pull in the clutch, I have checked the fuses????

    Either your sidestand switch (at the top pivot) is bad (easy to remove & replace, but many folks just bypass the silly thing rather than replace it), or the gear indicator switch on the top rear of the tranny is bad (potential PITA to R&R).

    If your neutral light isn't coming on, and the starting circuit doesn't think the bike is in neutral, you probably have a bad neutral switch.

    Paul's sidestand advice does not apply to your bike. It's not really accurate for his either.

    Question, then: I had a '97 1100RT, with the switch as I described (and I bypassed it). The GS of that year does not? (We're not talking about my present 1150.)

    The 1100 sidestand switch is like the kill switch: squeezing the clutch will not override it to allow cranking.

    The 1150 sidestand switch kills the Motronic (if also in gear), so the engine will crank but will not fire. Squeezing the clutch won't override that, either.

    The cranking but not starting "feature" of the 1150 is annoying. It could be fixed by wiring the input to the start button to the output of the Motronic relay. Since the bike won't start unless the Motronic is on, there's no point to letting it crank unless the Motronic is on.

    The other annoying feature is that the low beam light comes on and drains the battery a bit until you press the start button which then drops out the load relay. I'd rather that the headlights didn't come on until the bike was running. That could be fixed but it would take another relay energized by D+ from the alternator.

    Most probably your neutral light switch. I can't tell you how many times I've had my swing arm off for this issue. Such a simple thing but a pain to get to. Gear oil has seeped into the switch causing a poor contact. I pulled the switch, cleaned with electrical contact cleaner, then re-installed... a couple times. Last "fix" has held up for a couple years now. Paralever re-install requires you to do some pivot bolt thread cleaning and proper torque settings, etc. I've gotten quite good at this over the years with my 96 GS.
    P.S. I even bought a new switch once. It lasted about a month. Original switch is in now, working fine.
