Kids tired of that slow stock 120? Well, then this is THE KIT for you!
Fits all CAT models 2000-2009 only.
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 gears 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 clutch drum to swap out with your stock unit, a quick change
rear hub, aluminum sprocket and a #35 chain. 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 Arctic Cat 120 models from 2000-2009 with the stock Suzuki Engine. Try it today and more than
double the stock 7mph speed of that little sled! Typical speeds achieved
are 16-18 mph depending on snow conditions and rider weight.
