I posted in the other thread in the open forum, but I'll re-post here.

None of this makes any sense. I cannot think of one single reason that your quad would run in WOT in 2nd gear, but not in 3rd, unless your tranny was shot.
Have you tried running WOT in 2nd gear for long periods of time? Is it possible that your carb is running dry, but you coincidentally try to shift to 3rd gear at the same time, so you associate the problem with 3rd gear?
Have you determined that you actually have "power" in 2nd gear? If you're running like crap with no power in the higher RPMs, it would "seem" like it is running better in lower gears because you aren't loading the engine as much.
Your engine, carb, coil, intake, all of this stuff doesn't "see" gears or ground speed. If you are running WOT at 8000 rpms, you have the exact same airflow through your carb and reeds, the exact same fuel flow, and the exact same coil rotation speed whether you are in 1st gear or 6th gear. The components that affect jetting and how your bike runs DO NOT SEE GEARS. So it doesn't make sense to say your bike runs good in 2nd gear, but not in 3rd gear.
