    TE310 2011 bogs and dies when I give it a handful of throttle. Easing on the throttle is better, but the bike still doesn't run well and will cut out. Fuel pump works as I have tested it. I am assuming this is an injector/throttle body/fuel delivery issue? Anyone had a similar issue/know what to look for and test myself? I don't have access to iBeat personally, but last resort I can take it to my nearest Husqvarna dealership.

    You should get your own Ibeat set-up - the cable is cheap and you can download the software for free. Many threads about issues with 2011 and 2012 TE310 fuel injection adjustment and tuning.

    If you haven't already, try a new spark plug. Have you checked you've got a nice blue spark at the spark plug?

    Wriggle all wiring plug connections with engine idling. You'll hear the engine change note or speed if you've got a poor connection.

    Check inlet manifold for possible leaks. You can do this by spraying wd40 or similar onto the manifold, throttle body, etc. while the engine is idling. If the engine note changes at all, you've got a leak.

    also, on your era of xlites, the coolant temperature sensor (cts) has been known to get flaky and provide the ecu with errant info. $20. Supposedly, the older black sensors are more susceptible to failure than the newer white ones.

    I don't know of a CTS test on the bike. You might try unplugging it when warm... if the bike runs the same then maybe it's bad. Or short the leads with a 660 ohm resistor (guessing) to see if it runs better, which would indicate it's bad. [after the bike is warm- the theory I'm working here is that it's a negative temperature coefficient thermistor; if it's an op-amp or something else then who knows?]

    I've never have done any of these tests.

    Haven't changed the spark plug yet, will I need to remove the tank to change it or is there a special way I can get to it?

    The tank removes with one bolt. Seat, cross-over hose, pump connection, fuel line, reserve light connection. I'm probably forgetting something minor.

    Changed out the spark plug, no difference. Thinking possibly a clogged/dirty injector?

    yes, it could very well be a dirty injector. take it out and spray carb cleaner on both sides of the pintel.

    do not discount the CTS failure. do a search for this infamous component & its symptoms, and its numerous failures.

    good luck.

    Try re-calibrating your throttle position sensor. You can do this without iBeat. If the problem persists then you'll need to use iBeat or a dealer to troubleshoot the problem.

    TPS Quick Reset
    - Fully Warm Motorcycle
    - Disconnect the battery for approx 2 minute, then hook it back up again.
    - Turn the ignition key on.
    - Turn the throttle to full stop and then back again.
    - Turn the ignition key off, wait 5 seconds, and then turn it back on again.
    - Start the bike without touching the throttle.

    Get I-beat and check for faults.

    Was it running okay before?

    So I just tried recalibrating the TPS, and whilst trying to warm it up, after about 2 minutes the bike stalled. The pump started to sound more unhealthy as I continued to kickstart the bike. It restarted, but shortly after, stalled again. I can't get it started now. When the bike is cold, starts second kick every time and I can hear the fuel pump working perfectly. I've read that some pumps are faulty when they reach working temperature. Do I simply have a faulty fuel pump?

    Very possible, I've had three fail in 7 years.
