At around 45MPH the XP starts bouncing the front end. Trim does not eliminate this.... I can't even verify it is helping that much. LOL I have to lean over the front the get it to settle down then I can accelerate. I guess I'll get to the nitty gritty on my trim adjustment to make sure it is spot on but this thing is nasty to ride Wide Open... of course... that doesn't stop me.... LOL hints / help is appreciated.
