It makes tuning so much easier
The engine can be fully warmed up, hot even, and I can still reach my hand under the airbox and find the screw by feel without burning my hand! Excellent device and makes tuning the idle mixture a breeze! I just wish it came with packing and a spring.

CVP all the things
Worked great on my 2000 buell blast. Be sure to swap the spring over and make sure the packing doesn’t fall out of the carb.

No brainer.
No more fiddly screwdriver, no more feeling around to figure out if you gave it a half turn or the screwdriver slipped out. Easy adjustments, and highly visible so you know exactly what adjustment you made. Grab the EZ-Just idle screw while you're at it, you've probably spent more on grips than the two put together and this will make life a lot easier for you.

It Does Work On Other Makes of Motorcycles
This item was recommended to try on my Kawasaki KLR 650 and it worked well. Vendor should expand the title beyond Harley, as many other motorcycles use the same type of carburetor.

No need to carry a screwdriver with this . Easy to install and adjust .

Works great!
Doesn't come with hardware, however the screw has a flat head notche making it easier to count rotations. The screw is over sized just right and works great. I'd give 5/5 stars if it came with replacement hardware.

A must for Harley carb tuning.
Makes tuning so much easier! Trying to hold a screw driver in the stock adjustment screw is a real pain.

Just what I needed
This should of been a factory item. Except for EPA it might of been. Runs so much better. Thanks Guys.
