Khaos 850 not hitting peak rpm.

[Ridedayoop]

Bought a 2022 matryx khaos 850 brand new. Has about 60 miles on it so far in low elevation, (upper peninsula) I took it easy but now I’m starting to open it up more. Sled hits 7700-8000 rpm and if I hold it for a few seconds it’ll open up more and hit 8250. My 21 khaos never did this. Is it normal during break in to not be able to hit peak rpm with the extra oil being added above 5500 rpm?

What elevation?

I have the same sled, and ride relatively low elevation. My Khaos behaves differently then you describe, even through break-in. I have factory low elevation clutching with 70g weights. At 3000', in a foot of powder or so, it'll hit 8300 rpm and quickly settle in around 8150 - 8200. Above 5000', it struggles to break 7900 rpm.

What clutching do you have?

Ya, sounds like some clutch work needed

I ride at 3k to 6k and still in breakin mode and mine pulls 8450 with a clutch kit

Check the throttle cable adjustment.

Check the throttle cable adjustment.

Yup like TRS said make sure you can hear the throttle bodies hit there stops fully open.

Yup like TRS said make sure you can hear the throttle bodies hit there stops fully open also check your belt deflection. Most sleds come all out of wack. If that belt is not properly adjusted it won’t shift properly

If your only at 60 miles I wouldn’t worry about it too much yet. I’d wait till at least over 100 miles before doing too much to clutching. Your in the UP, pretty much sea level to 1,000 feet? You can get your belt deflection, alignment and belt to sheave clearance spot on. Some are coming way off from the factory.
