Cory,
Try taking off the flywheel weight for your next test. I'm assuming it's a steahly so it comes off pretty easy. They soften the power quite a bit. It might be what you're looking for. Take it for a test ride with no weight, then drop your needle all the way and try it again. As for the needle, I am assuming you are running the N82M (stock) needle. If you will always stay at altitude, you might want to go all the way to the N82R. When you get the jetting right the power should be very linear and controllable (but also dump you on your ass at times). Cam.
