KC Pro west specific rules

Semi-Pro gearing is now restricted, you must run a 3.0 on Arctic Cat and 2.88 on Polaris, but the combination MUST be 15/45 for Arctic Cat and 16/46 for Polaris. Also, you must run a green slide.
There can be NO ORANGE on the snowmobile per ISR safety rules. This includes decals, reflectors, seats, springs, numbers, etc. If it is orange it has to come off the sled or have tape placed over it. – This will be enforced, no exceptions.

In the B120, Stock and Improved Stock classes the taillight must be working when you come to the starting line. If the light does not work you will have (4) minutes to get it working or you will be a scratch from that heat or until it is working.

B 120 does NOT require a rev limited

Amateur, Stock and Improved Stock all REQUIRE a functioning rpm rev limiter.

Corner people are needed at each and every race, so please do your part as a member. Don’t forget we are all in this together.

Your helmet must be 80% orange , per race directors discretion
