Looking for more juice on your Polaris RZR 170? Look no further, upgrade your vehicle carburetor to get the performance your SxS deserves! This carburetor is Genuine 26mm Mikuni Carburetor. The carburetor is much larger than the stock OEM carburetor which is 21mm. This offers more capabilities for tuning. Providing more air and fuel for increased performance on bigger bores or even the stock OEM engine. This is one of the best upgrades without digging into the engine itself. The carburetor will need to be tuned and adjusted to your location. It will also require an aftermarket intake mod to allow fitment and a new throttle cable. This is an aftermarket performance part and will need to be adjusted/tuned to make work. Our kit includes a coupler to fit the intake manifold for easier installation. Please contact us if you have any questions.
