could anyone who has done a big bore kit on a grizzly 600 tell me how much difference it makes? which kit did you go with and is it worth the money? after all the work, would you do it again if given the opportunity?

 

Check out Highlifter. they prob do more 4x4 quad work than anyone else. Very good to deal with also.

 

I would be curious to know the answer to this as well since I am thinking about getting a grizzly 4X4 and I would want to do some performance mods to it as well.
