STAGE 2 - 250 HP

The Stage 2 adds 50hp over stock configuration.

With the increase in boost pressure, the Stage 2 will work with our Precision EFI or any 2.5’’ free flowing exhaust system.

It will transform your snowmobile into a real beast!

The throttle response of this reflash is just insane and it will perform perfectly in any condition. Heavier weights in the primary clutch are a must!

The Precision EFI knock system is include in all our reflash.

Please take note that this power package requires the addition of some adjustable ramps in the primary clutch

Ramp adjustment starting point 
For a stock spring and helix combination in good condition, to achieve the target RPM. Please note; a modified spring and helix combination affects the final result. Therefore, we cannot provide settings for every application.


The test should be performed as follows: accelerate quickly but gradually to avoid track slippage. While accelerating, wait for the RPM to stabilize, then take an RPM reading. If the RPM is too high, add weight; if too low, reduce the weight. 
Note that surface conditions vary and affect RPM.

- Target RPM: 9000 ; Springs and helix cam SIDEWINDER-CLUTCH-COMBO are strongly suggested 
- Dalton QaY-70 set to a total of 73 g (use purple Loctite)
- A screw head flush with the top of the hole (at the heel) is the most common setting.
