I had my doubts as to the quality of the machining done on this product, when the sticker stated made in China. When installed on my FXR, the carb ran so poorly, that I compared all dimensional aspects with a blade mic to the original air fuel mixture screw. To say this item is not dimensionally within spec to the factory air/fuel screw is an understatement. For the price I paid, I’ll put it in a lathe and bring it into working dimensional tolerances myself. If you don’t want the hassle, pay the extra money and go with a Yost fuel screw.

Quality, ease of installation and performance is worth every bit of this $8 upgrade. So nice to be able to fine tune the idle mix without having to remove the carburetor, especially after rebuilding or replacing my Harley Fat Boy carburetor.

Loose fit in my stock CV carb from a 98 Harley softail. Other than that it seems pretty well made, and the included mixture packing replacement was very welcome. We'll see if it leaks with a little plumber's putty on the threads. I'm pretty sure it would leak with Teflon tape since the fuel would degrade the tape pretty quickly.

Fit Perfectly and works great in a 1998 (Softail) and 2003 (Dyna) CV Carb. Make s adjusting idle mixture so much easier..

Solved the back firing issue. Just note there are no instructions but easy to figure it out.

Fit perfectly in my 05 twin cam 88, bike runs perfectly, easy adjustment. Yet to see if it stays in place. But feels pretty secure. At this time I would recommend!

No problems with the needle being the same as my factory CV40. Still can't adjust it on the go with my stock evo flh air box.

It came super bent, and you can’t use this product when it’s bent, so i wasted money and it’s going in the garbage. I can’t get a refund either. Just dont even bother buying it
