I have a 2006 griz 660 mostly used for hunting, this september we hunted elk for 3 weeks so I got some good use out of the bike, there are a couple thing I do not like, its extremely loud! If there is a after market exhaust I would love to know where I could get it. The other thing I noticed is the lack of power, a few times I was stuck in the swamps and in low the motor has a hard time getting the tires moving? I have 26inch mud lites, it seems that low is not low enough? would a clutch kit help? I am happy with the top end power. Thanks for any help...Jason

 

Yhea add a clutch kit from EPI to help with low end torque for sure. check out
