Thinkin on doing some mods to the Grizz and wanna know if it's worth it

FMF powercore or powerline on rockeymountainatv, is this thing loud? I don't wanna make the quad obnoxious

K&N Filter, does it help much? worth the $?

Jet Kit manditory with above yes?

Clutch Kits, I will be going 27" tires soon so this is a yes, yes?

Other than that is cams/pistons worth it? maybe a bit larger piston for some xtra compression?


all these mods, would the Grizz make a Bomb 800 nervous? Or do I need to make it larger CC with a bigger head?
