A replacement (extended) fuel screw for your DRZ or KLX.
John says: "Don't be without it. The extended T-Handle Fuel Screw allows you to make easy, on-the-road carburetor adjustments required by elevation changes. You'll be glad you have it."
Note: the fuel screw comes naked and requires the OEM o-ring, washer and spring.
It is for the stock carb on the S Model.
