Warm engine, low RPM sputter

[UpsideDownTom]

Hi Gents,

Need some help here. Brought my 07 Buell Ulysses with me when I moved to Australia. She started acting funky a few weeks ago. Called the Harley dealerships and none of them want to touch it. So I'm pretty much on my own. I have some mechanical sense, a service manual, a decent set of tools. Ready to have a go.

Here is the issue. After the bike gets warms (~20-30 minutes of riding), the bike sputters and hesitates at low RPMs when I give it gas.

Thoughts?

Thanks in advance!

Intake seals, or a sensor (IAT,o2 or something along those lines)

There is never one answer for this.

I'd start easy then get to intake seals & o2 sensor, maybe even tps/ or CPS point timing

Could unplug your rear head temp and see if it smooths out. Could be cutting rear cylinder

Thanks. A local guy suggested the intake seals, and I ran this test [https://www.youtube.com/watch?v=5MvohPCZazY#t=150). ]. I didnt hear a drop in the RPMs, so can I rule the intake seals out?
