Sport Rider Package All the Speed You Need at an Economy Price !!

We only run the lighter #35 chain with our Economy Speed Kit.

Our competitors still use the heavy #40 chain. Huge Difference!

                             

Is your little rider bored with that slow 7mph mini sled?              (SOLD SEPARATELY-THIS IS A MUST HAVE FOR CAT/ YAM / MZ - CLICK FOR DETAILS)

Not racing but just want some more speed at a reasonable price?

Well, then this is THE KIT for you!

There are two major problems with the stock 120 sleds. One is the motor only turns about 3,000rpm before the stock governor kills the party. The other problem is with the stock gear ratio and the heavy #40 size chain coupled with a 10t stock front sprocket.

Our Economy Speed kit fixes both!

Governor Spring-Most people know that the stock spring is too weak. And a lot of people think it's okay to bypass the governor with a zip tie or piece of wire. BAD IDEA! The problem with doing that is if the motor is then run at a constant too-high rpm with no relief on the governor, that little plastic governor gear down in the engine is eventually going to break, scattering parts and doing extensive damage. The correct way to do it is to put a proper tension spring which will allow a safe 5,000rpm and then open to relieve the governor and also keep the piston from hitting the valves as well.

35 Chain Conversion Kit-Simply put, The stock #40 pitch size chain doesn't work! With the smaller 35 pitch chain we have found that there is far less less rolling resistance than a stock #40 chain and sprockets have. This is because the rollers are smaller and the sprockets have more teeth on them. This reduced resistance results in better performance along with reduced chain wear and noise. This easy to install kit will set you up right. Includes a new #35 pitch clutch drum to swap out with your stock drum on your OEM clutch. The clutch engagement rpm will be the same as stock, but the new revised taller gear ratio will deliver several more mph than stock on top end. Works on all years of Ski-Doo, Polaris and Arctic Cat 120 models. Try it today and more than double the stock 7mph speed of that little sled! Typical speeds achieved are 16-20 mph depending on snow conditions and rider weight.

Racer Package The Next Step Up in High Performance!

This kit includes the High Performance Race Clutch coupled with the Power-UP Intake Kit. While similar to the Economy Speed Package it adds increased Horsepower with the carb mods and tune-ability which is necessary when racing or if you just like to tinker.

Racing Clutch-High Performance unit with a higher engagement rpm for better take-offs. Excellent as a replacement for a worn out stock clutch as well as it does for racing applications. This clutch is very durable as well.

Power-UP Intake Kit-include a new heavier governor spring with the correct tension, a machined aluminum velocity stack for maximum airflow and a really slick adjustable carb jet which allows you to dial the jetting in easily with just a turn of a knob. These Power-UP  kits have been thoroughly dyno and race tested with very impressive results. Once installed, the motor will rev about 2000 rpm higher with the new spring and you can now adjust the air fuel mixture for maximum HP & RPM. The new power increase will also allow the little sled to pull the taller gearing for even more speed.

#35 CHAIN BREAKER

Our gear kits include 40" of #35 chain which must be cut to the correct length for your machine and sprocket combination. While there are several ways to do this including grinding off one of the pins, This #35 Chain Breaker uses a pin press to "break" chain to the desired length. Also has a flat press used to assemble chain without a master link. This way a chain can easily be made longer if desired for larger sprockets. A quality addition to any tool box!
