I'm looking to purchase the wiseco piston kit 102 mm bore that increases the grizzly to a 686. Will i be able to feel a difference with the pistons if i already have other mods such as an hmf, dyno jet kit, cdi box, k/n air filter? Basically, is it worth buying this kit? I'm also looking into a hot cam for the grizzly from mudcracker. Will that increase the performance when put together with the piston kit? I appreciate any input you can give me

 

do a search for something posted by Silverbear. There will be a link to his website and maybe an email address. Ask him about it. He did his, and said it was pretty awesome. I'm sure he would be more than happy to answer your questions too.
