FX450 stumbles off idle. HELP!!!

I'm new to both Husabergs and fuel injected bikes. Point me in the right direction.

I posted this in the Mechanical forum too. Sorry for the double post.

I just bought a 2010 FX450. It had a new fuel pump installed last year. It runs fine at high rpm, but when I blip the throttle off idle, the engine sputters and dies.

If this were a carb bike, I'd start by checking the accelerator pump, fuel screw & pilot jet but I have no experience with FI bikes.

So far, this is what I am planning to check: battery voltage & conmections, the spark plug & cap, the fuel pump pressure, the fuel pump filter, the in-line fuel filter, the fuel line inside of the tank, and the TPS.

Am I missing anything?

What is the TPS voltage or resistance suposed to be?

Thanks for any tips or advice.

Great! Thanks.

Does anyone have specs/details/instructions to adjust the TPS? I have no idea what the voltage or resistance should be for a FX450.
