Hello
I picked up a 05 660 grizz. Beat up.
Fixed it up. Runs nice now. I need help on clutching. It has a worn out dry primary. I haven't weighed the weights yet. Also a purple 2nd clutch spring. Tires are 27in executioners. Short lift with elk suspension.
How do I set up the clutch to run these tires? I care not for top end. I like mudding and crawling thru the bush.
Any help is very appreciated.

Service your primary sheave and add
1.5 or 2 mm of shim. It will give you a lower initial cvt ratio (more torque)
, at the cost of some top speed

For me torque is key

You need to raise the pulley ratio, look in my signature, your '05' will take what my '06' is running.
You'll need a machined primary movable sheave and some shim for best ratio, then lighter weights will make'er scream if m.p.g. is no concern. Then your axles will take a beating.

Like I said it was beat up. Had to weld frame to get the diff in place. I put new high end axles in so I hope they can take the beating.
I took the clutch apart. There is a shim.
I put on a new oem belt.

Thanks to everyone here. It sure makes you feel like your not alone

I like torque too. How do I get it. Catwalks would be cool.
Thanks.

You'd want a machined sheave, as well as the max amount of shim, lighter weights, and a stiffer spring.
