## What it fits

The store lists a part under each bike or engine model it is meant for (the categories below) and may name models in the description. Do not assume it fits a bike or engine that is not named here; ask the store first.

Where a fitment line says "All", it means all years of the model named on that line, not all bikes.

## Description (the store's own text)

This awesome upgrade blends OE style fitment with a significant upgrade in the 22mm Mikuni carburetor. This kit is intended to work with the stock intake and airbox! The throttle cable provided is extended for use with tall handlebars. A high flow UNI air filter for the stock airbox tops off this performance upgrade for a noticeable improvement over the factory carburetor.
