Default Unusual idling
Running Fuel Moto's 107 bore kit, TW 777 cams, Level B ported heads. when it sits idling for a minute it sounds like both cylinders are firing at the same time. I goose the throttle and sounds normal for a while then goes back to firing at same time. Fuel Moto loaded their tune on the power Vision I bought from them, and they said I will need to have it Dynoed and fine tuned as soon as it gets broke in. Can the tune be the reason for this unusual idling? No problems with riding, just at idle.

You know it's impossible for the cylinders to fire at the same time. You don't need to wait to break the motor in before you have it Dyno-tuned.

Are you sure it actually isn't dropping the rear cylinder? If she's hot, the software will do it at idle. Mine does. I forget the acronym, it's in the owners manual

Here's what she sounds like. And yes, it only does it when it is hot.

As said above, "Parade mode" most likely.

EITMS...? Engine Idle Temperature Management System. Rear cylinder drops off over a certain temp.
