    CBR929, bike shuts off when taken out of neutral

    Bike was a racebike. Wiring all hacked up. But, it worked. Aftermarket tach/gauge, no original cluster. Rocker switch for on/off. Killswitch works. No wiring going to clutch lever switch. Wiring hasn't changed that I know of since I got it.

    So I had to swap the motor due to it slipping out of gear. Put the new motor in, runs great.

    Only issue, whenever I put it in gear, it kills the bike. Like, killswitch kill. Then, no start until you put it back in neutral.

    Checked/swapped/bypassed the kickstand sensor, no dice.

    Any ideas on what else it could be?

    I wish there was a logic tree for the ignition kill system on this bike like there is for the fuel pump.

    Clutch or side stand switch or wiring. Don’t know if the switches are no or NC, but you probably have a cut wire, if the switches test ok. My guess.

    Sounds like a clutch switch.

    Yup, gotta be it. I’ll trace it out and jump it tomorrow, see what happens.

    Somehow, previously to this motor swap, the clutch switch was jumpered somehow. Of course, I can't find any evidence of this.

    Jumpered the two pins going to the left side switchgear (clutch switch), and boom, she'll crank over in gear. Also found an intermittent kickstand switch connector (switch itself tested fine previously, but the connector was junk), so I'll swap to a known good one.

    Still a mystery how this thing ran before.

    Going to wire in the clutch switch using the connectors for the front brake light switch.

    Funny story... We were working on a Volvo 242 for lemons and the same guy who caught that bike on fire also caught the Volvo on fire while soldering wires... Coincidence lol?
