This kit includes 4 main jets (sizes 80, 85, 90, 100) and two pilot jets (sizes 15, 25) to help you easily get your carburetor dialed in. The jets in this kit are commonly needed for Arreche carburetors in the 19/21mm carburetor range. These jets will work with all other Arreche carburetors but the jet sizes may be out of the range or needed jets.

Note: 19mm Arreche carburetors come with a 95 main jet and 20 pilot jet which is why they are excluded from the kit.
