i just added a 12:1 je piston to my grizzly and it was a difference of night and day. now when i floor it on payment it will lift the front end off the ground. i have to let off the gas to keep it from going over. there's not alot of info on aftermarket pistons on here for grizzlys so i thought i would add this for anyone interested.

 

How does the power compare to say, a vtwin? Such as a Kawi 700 or a Bomb 650.
