Fits DRZ400S in parts

Bought for my DR Z400S. It was difficult to remove and I would recommend being very careful not to lose the old one. It is easy to mount on the bike.

Pros
  • Quality construction
Cons
  • Expensive

Fits and works well. Good price

Fits well and works well. Might not be as good as high end fuel screws, but you don't usually need to adjust it too often once it's installed. Excellent price. Happy with purchase and quality

Pros
  • Everything is fine!
Cons
  • Damaged

DO NOT put this in an FCR Slant Carb!

Wrong threads for old Keihin Fcr canted carburetors, completely ruined the carburetor trying to fit one of them very very VERY carefully, I barely got the first thread, messed up the internal threads

Pros
  • Tough finish
Cons
  • Security

Needs Improvement: Motorcycle and Powersports

Mehh. Someone must have done a great job there. I had to use an old spring because the new spring had too much tension and actually stripped the threads on the aluminum shaft due to the pressure. Make it out of steel and I'll buy it again. Now I use the old tuner.

Pros
  • Absolute Legend
Cons
  • High Price

Not recommended Best in Carburetor

Installed on my 01 YZ250f. The grooves cut into your thumbs when trying to tighten the screw (because the spring is very stiff). In addition, the carburetor on my model bike has to be loosened and turned in order to adjust this screw at all. I give 1 star. Not a very high quality product in my opinion.

Pros
  • Price
Cons
  • Small Parts
