The throttle will give some slight hesitation and I know that points to the ECU or adjust the throttle. I've checked the throttle and it's fine, no major slack or kink. Well, heck.

Venom bought up a bunch of stock due to EPA regulations causing many of Lifans bikes to not be legal for the immediate future until they can pass certain regulations. You likely got shipped a bike from that pool of vehicles with an older ECU and Venom was simply not aware of it because they knew all of the bikes they were shipped had the upgraded ECU, and yours simply didn't.
