Answer
Hi Bruce,

That's an awesome motorcycle.

I suspect a problem with fuel delivery (fuel pressure). May be related to a system defect or failure, varnished fuel obstruction, or other.

Get a copy of the service manual and start investigating. Victory's are so new, I don't have any experience with them.
