🔧 NICECNC Gold Extended Fuel Screw Air Mixture Carburetor Adjuster for Suzuki DRZ400S/SM 2000-2022 (Part 13279-33E00) Review

A bit nervous about the installation but everything works fine, no leaks, much easier to adjust the fuel now, thanks! Used on a 1999 KTM LC4 640 Enduro with a Mikuni BST40 carburetor.

Perfect for 2018 DRZ400s carburetors. I just wish it had numbers or a mark on the head so I know what a full turn is. I drew a small black line with a marker to reproduce this.

Excellent finish and finish and works great in my DRZ400. I made a 3X3 mod with JD's jet kit and I turned this screw 2.5 turns and it works great.

Good communication on shipping. Crew is the perfect tool to adjust the idle speed of a Mikuni BST carburetor via the originally inaccessible screw. I highly recommend this upgrade.

Installed with inkjet kit on my DRZ400. It only took two turns. Fired it up for the first time and works perfectly. Maybe I can make changes when I get to the top. If your carburetor is off, you will need to add this fuel screw. It makes sense.

Seems to work fine on my DR650. It has the same threads as the OEM bolt, but the profile and taper are slightly different. I tuned mine but it doesn't have the same adjustment as the OEM bolt but that's why we buy a longer bolt for easy adjustment right?

The original was too far in the tube and could not be adjusted on the machine. I had to unscrew about 3.5 turns instead of the factory 2.5. The spring didn't stop that part from unwinding while riding. So tape was used to keep it in the right setting.

There are no complaints about this product. Installed it on my stock DRZ with a JD jet kit and full MRD exhaust. I'm about 3km above sea level and have it set to 2.5 revs. It works amazing, I didn't think this bike would ever work so well. Unscrewing the original screw was difficult, I drilled too deep into the dowel and removed most of the head. I had to drill the top of the screw and unscrew it with a torx cut in the hole. It worked, but be careful with this when trying to unscrew the stem…
