QUOTE (kawiking @ May 23 2008, 11:43 AM) index.php?act=findpost&pid=915would u say thats worth 10 hp.. ?

thats what somebody told me...

You are looking at a 10lb difference.

If you believe the general consensus, 1lb of rotating mass is = to 7lbs of stationary mass. Likewise, 7lbs of stationary mass takes 1hp to move. So if you believe these generalities, 10lbs of rotating mass=70lbs of stationary mass=10hp

You think/know of someone that has dyno'd one to the other?
I'd say at the very least, it'll get your back tires driving and out of the hole faster fo sho!!

Kinda what I was thinking, wanted reinforcement...
You guys have a dyno at your shop, don't ya?

You're not actually pushing the mass of the bike...I gotcha, it's being simulated by loading the tires with resistance from the barrel.

I dident really notice any e.t drop or mph gain when I switched. more then likely its from the crappy track we run on but. I can tell you guys this much I spin a hell lot more and can pull more gearing then with a stock axle.
