Are you frustrated while trying to adjust your fuel screw for the best idle and cruise on the Suzuki DR-Z400? Your quest for a magic 90-degree screwdriver is over!
Just replace the stock fuel mixture screw with this extended one. It's so much easier to fine-tune your bike. What does this screw do? It sets the air-fuel ratio at idle and early throttle opening by allowing more or less fuel.
It's a great addition to installing a jet kit or any other performance mods where you must re-adjust your carburation to the optimum. If you are travelling temporarily at a higher altitude than usual, this would also help lean out the low-end.
Note: This part is made specifically for the stock carburetor, the Mikuni BSR 36. It won't work if you have something else like the Keihin, FCR or CVK. The kit includes a washer, o-ring and spring.
