Two threaded crankshaft inserts for "short" and "standard" applications. Rear exhaust. Molded LCP (Liquid Crystal Polymer) body slide valve carburetor with high-volume air filter. Blue anodized aluminum cooling head with molded head protector .
Some notes on slide valve and rotary carburetors. Rotary carbs offer a larger response in the middle of the power band. This works well for off-road applications when throttle response must be varied. Slide Valve carbs provide greater response at the beginning and end of the power band. This works well for on-road and racing applications for fast take-offs and high speed.
