I got a new 09 M8 HCR last month. The most I've ran it for was to load it aboard the truck, then offload to my garage. I discovered there is apparently a special break-in procedure for this sled although the dealer I bought it off of can't confirm it. I found this on snowest

1. The dealer must ensure the first tank of fuel is
premixed at a 100:1 fuel to oil ratio.
2. Check the coolant level and fill if necessary (see
Operator Manual or Service Manual for instructions).
3. Elevate the rear of the snowmobile on a secure,
shielded jack stand.
4. Slowly vary the engine RPM and throttle position
gradually from idle position to a maximum of
6000 RPM until the Coolant Temperature Warning
Icon stays constantly lit while making sure not to
exceed 6000 RPM. Continue varying the throttle
and RPM for an additional 1-2 minutes.
NOTE: Make sure to lubricate the slide rails with
water or other appropriate coolant/lubricant to prevent
melting of the wear strip.
5. Allow the engine to cool to ambient temperature
(at least 30 minutes).
NOTE: Repeat steps 2-5 at this point.
6. As part of the standard operating procedure, operate
the snowmobile during the first 1 to 2 miles
under 6500 RPM to properly warm the engine
prior to extended wide-open throttle use.


Does anyone know if this should be done or not?

Thanks

i just bought a 2010 M8 HCR and i was told by the dealer to.

1.mix 250ml of Arctic cat oil in the first tank of fuel
2. drive it reasonable no WOT and varying your rpms

only put fuel oil mixture in tank if your going to burn a full tank so it doesnt clog up the filters and drive it like any other break in period.

Thanks for the reply. AFAIK, the 09 and 10 engines are slightly different and there was no 2010 special breakin procedure.

Oil in the tank will not clog your filters, I run 28:1 in my tank every day.

If you're the type that can't hold off & break in the sled properly, I'd do the stationary breakin procedure. The only purpose to that is to give the dealer a bit of control over how the sled got broken in.

That said, break in on the 8 is minimal, the 1000 needs much more care & patience.

my dealer told me when I bought my xfire 800
let it idle a few minutes until it is pretty warm, shut it down, let it cool down for an half hour :sleeping:
then it's done, just drive :sledder:
he told that they will make best performance with that procedure :bill:
