660 clutch suggestions

I have a 05 660 and was wondering what clutch work would I need primary or secondary spring or both springs, which color springs and what weight rollers would I need? I am new to the Rhino and Yamaha. I ride in trails and mud.Any help would be great.

Tire size? If stock 14G rollers and an orange spring will be pretty good...

x2 and a machined sheave will add several mph to the top end and lower the rpm in the middle speeds

you really should add a wet clutch kit also with those big tires

if your motor is stock, do not go below 14g weights. but do go up to a EPI gold secondary spring.

12gram weights were recommended and sold to me for my 06 660. The only mods to it is a utvcrap sheave and a dynatek cdi. Im also running 25 inch bighorns. You guys think the weights will be too low?
