I just bought a New 2005 Grizzly im needing to know what would be the best mods to make at this point in time .. Im going to order ITP 589 Tires 27" i just need to know info on what sizes .. Will i need a clutch kit ? please any input would be helpful

 

I would look at the highlifter outlaw clutch kit. You will not be disapointed. Power kits with K&N filters, prefilters and dyno jet kits are also a good bet.
