Polaris 120 Engine Parts

There will be more engine parts listed as I have time to add them. Thanks for your patience.
The GEN5 valve spring is the best valve spring available today and 100% ISR legal for both Ice Oval and SnoX racing.
The "blue tinted" valve spring has a slightly tighter coil which is not ISR legal, but accepted in most snoX venues.
The OEM valve spring is exactly that, and not many customers buy these when you can get the others for 1/4 the price.

KOSO Rev Limiters (ISR LEGAL)

As of the 2014/15 season, rev-limiters are now required to be used on all stock 120 class races. These KOSO rev-limiters restrict the maximum RPM to 6850 and are the only ISR approved rev-limiter devices.
This rev-limiter uses a 9 volt battery for power so there is no power required from the snowmobile itself.
A very simple three wire hook up to install.
This rev-limiter is for the Polaris 120. The Arctic Cat and Yamaha are different.

KOSO Mini RPM Tach (with recall)

This meter can be easily install on about any engines. Just wrap the RPM signal wire around your spark plug wire, set the number of cylinders… that’s it, you’re ready to go!

Spark Plugs

Standard and Iridium NGK spark plugs for Kitty Cat and all 120cc sleds. Order on-line or call 651-485-3771.
Iridium plugs last longer and have more spark surface for better fuel ignition.
