My 03 was used and set at +25 for Prescott, AZ, and it popped quite a bit when you chopped the throttle. The 04 quad was brand new and set at -4, way way too lean.
My point was you don't need to start or run the bike to change and set the trim. It's not a long drawn out process, and a busy Dacuti/HD shop might squeeze you in for a quick adjustment if you have some numbers in mind, and can tell them what CPU your Gas Gas has.
