‘11 M8 Low Elevation clutch help

[Arrow2013]

Just picked up a used ‘11 M8 sno pro with high altitude clutching. I live in Minnesota and need low clutch adjustments. What is recommended? The sled has a SLP intake and a after market can. Anything will help as I am new to the snowmobiling world.

There is a chart in the engine bay with recommended weights & springs for different elevations. Lower elevations require greater clutch weights. If you're not set up to work on CVT clutches, it is probably best to let a sled shop go thru both the primary & secondary clutches as well as the DD gear box. The DD gear box needs an improved bearing if it has not been done already.

70-80g adj weights,cat green primary & formula x-1 secondary set up

72gr / adj are nice. 40/38 helix

Would I be able to use all the same springs and helix and just change out the wieghts? Or do I have to replace everything?

Springs are prob yellow white & an orange, they're fine. 36 helix not so good, 44/40 or like thunder said. 70-74g weights get you ballpark

If you want budget, just do weights. But backshifting, on/off situtations and how it moves through the shift-out will no be ideal. But if you don't mind that so much, get the weights set-up so you are seeing around 8k rpms and have fun.
