Dynojet jet kits increase horsepower, improve throttle response, smooths out powerbands and in many cases improve gas mileage as well. Since most carbureted motorcycles, dirt bikes and even ATVs have to pass some type of smog test by the manufacturer, they can be 'choked up' stock and a jet kit is just the answer to breathe more life into your ride.
These are guaranteed authentic Dynojet jet kits designed for U.S. spec bikes and may not work properly on machines sold elsewhere in the world. If you are an international customer, it may be a good idea to check with a local mechanic to see if this kit would work on your motorcycle. Euro spec jet kits are available for most bikes, but we are not allowed to ship kits into Dynojet UK's distribution area. Other countries, such as Asia, Australia and others are fine. Also, there are some CALIF kits for California jetted bikes, and HI ALT (high altitude) for bikes that live above 4,000 feet.
