If U are keeping the 30's, buy a QSC kit or pick up a Dalton kit, and add a yellow/black dalton driven spring. The tan spring has the same engagement RPM as stock, but the same finishing rate as the green/yellow dalton. If U ride fast and hard get the dalton kit, if U crawl over stuff and trail ride alot, use the tan spring instead of the green/yellow spring that comes in the kit....
Dalton kit will not help and XMR as much as a std Outty. The XMR already has 6 Renny weights in the primary. The Dalton weights are exactly the same profile and weight (when empty) as a Renny weight.
I would add the yel/blk secondary spring, tan primary spring and run it....cheaper than buying the weights. (kit)
Dalton with the heavy spring is fantastic in my outy, have 30's on with Gorilla axle's....thats a must with the clutch kit....you will snap your front end eventually. lots of fun last summer limping home in 2X4
The QSC clutch kits are far superior to the dalton setups for that machine. I have a few friends with outy 800's and the QSC kits just seam to engage smoother and make more power. If you have a few extra bucks laying around QSC just came out with a complete replacement clutch setup. It adapts a Polaris clutch to work in the outlander and it is pretty sick.
