Thanks for the help guys. I know how the CVT works. I have experience with my Yamaha Grizzly. I don't really care about top end. It's cool to say, "Yeah, I can do 70," but that's not important to me. I chose the ZForce V-twin over the Yamaha Wolverine single for low end torque for mud tires instead of top end. The engine has plenty of power, but the clutching is all wrong for deep mud. I'll loose a lot of top end with big heavy mud tires anyway. I want to gain as much low and mid range as possible.
I don't have any experience with an adjustable secondary spring. Does it really make a big difference, or is it more of a fine tune mechanism? I guess I'll give it a try as soon as I get time.
One more question. Does the CVT cover have a reusable gasket or do I need to get a new one before I start?
