Stage 1 adds 9hp to your Polaris 850.

With this 9HP gain, you will also get a better throttle response.

This package has been tested and developed for trail and mountain riders.

You will have to install some adjustable ramps to lower down the RPM. The ideal engine speed is around 7900RPM

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: 7900
- Adjustable Ramp Kit Dalton QaP-5 (73.5g) set to total of 74.5 g (use purple Loctite)
- A screw head flush with the top of the hole (at the heel) is the most common setting.
