    06 Ulysses XB12X stalling on cold startup and at warm idle

    Updating this thread for closure. During the first stretch of sunny weather in early 2021 I replaced the leaking intake seals, the spark plugs, and the ignition cables then TPS reset. The bike hasn't stalled since and obviously rides way better. The only mystery I never solved was the dropping...

    06 Ulysses XB12X stalling on cold startup and at warm idle

    Wait, the primary plug's tiny magnet was covered in shavings so the rotor's magnets are probably covered too. Didn't think about that at the time. Man, I'll have to take out the clutch, chain, and rotor for inspection sometime soon.

    06 Ulysses XB12X stalling on cold startup and at warm idle

    It's got the factory bolts on the flanges: one side is socket cap allen, the other is hex head. Nice tip with the fuel line for the rear. Swapping the plugs and wires myself is fine, maybe even the throttle body, but I don't want to buy a compression tester or a leak-down tester. And if the shop...

    06 Ulysses XB12X stalling on cold startup and at warm idle

    First off thanks for the suggestions! Back to share what I found: Front cylinder spark plug cable was loosely connected on the coil side. The terminal was broken and rusted. New cables on order. Ignition coil's primary and secondary ohms were to spec. Rear intake manifold seal leaking...

    06 Ulysses XB12X stalling on cold startup and at warm idle

    New concern, what seems like an excessive amount of lukewarm air and oily mist is continually exhausted through the positive crankcase ventilation breather tube (I removed the mini-airfilter for now). I couldn't find any videos of open breather tubes to compare mine to so here's a short video...

    06 Ulysses XB12X stalling on cold startup and at warm idle

    First contact! You're too kind Cooter. Just reset the TPS again (before I saw your reply). I did follow the procedure each time, should've clarified. Then went for some short errand rides. First ride when taking off it was bucking like a bull for a few blocks before settling down to idle at...

    06 Ulysses XB12X stalling on cold startup and at warm idle

    Bike: Recently purchased 2006 Ulysses XB12X, 18.5k miles, K&N air filter, breather re-route with filter, Termignoni exhaust without valve, stock BUEIB ECM (no idea if the map is stock). Problems: Start cold bike, idles for ~1 second, then stalls. Start cold bike, open throttle to a steady 2000...

    06 Buell XB12X ulysses stator or regulator issue

    That light gray connector is the speed sensor connector. The #77 voltage regulator connector is the black 2-wire connector behind the rest, see this diagram from the manual:
