Fits perfect
For the cv carb on my harley davidson perfectly and makes it so much easier to adjust. There is no leakage and inhaling it was super simple.

Fit good but time will tell if it worth a crap or not

Better than a screwdriver.
Edit: sept 9th 2020.... still going strong. Was worth the money... Installed on a 1998 sportster 1200 Custom with the stock CV Heihin carb. Before installing I recommend cleaning the part with brake cleaner before installing as mine had a little chuck of brass and some small brass shavings in the threads from when it was manufactured, just to prevent anything thing foreign from entering and clogging your jets... no big deal you should always thoroughly check and/or clean any part prior to installing. Furthermore they do seem identical and the new one threaded in no problem. I did NOT have any issues with the spring provide as some other reviews said it didn’t fit. The only small thing I saw that could be an issue is the diameter of the very very tip is slightly bigger (like 1000ths?) which may or may not have sealing/seating issues but I’ll update once installed and tinkered with. So far I’d say it’s worth the money, will update if views change. Ride safe🤙

Completely different taper to the stock idle mixture screw, didn’t seat properly

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!

It is good quality.. except didn't thread all the way down because the tip is slightly larger. (early evo big twin cv 40 carb)

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.
