There was a very slight "bog" down in the low end, Danny had more of an issue than mine did. We leaned his motor and it got to the point where it was driveable. My biggest concern was the loss of power, it wasn't a whole lot, maybe 85% of what we are use to down here. I was wondering if you can gain that power back by changing the shimming?

Please don't miss understand the post, personally I think the Alphas looked the best out there. Granted a lot of people broke during the main, I still took the "W" by about 3 laps. The air was really thin and was just wanting to know what to do next time I was in those conditions.

Thanks to Mark Mayhem, an Alpha user blew his motor during his main, naturally he was "bad mouthing" Alphas. Long story short, Mark took a look at his plug and it had dirt in it. Hopefully he won't give up on the motors!
