I love all sorts of cool gadgetry....as long as it serves a purpose and works. Bobber turned me onto this several years back. I put one on the 500 and love it. Its simple, and makes life easy.

How many times have you taken off in the cool morning...rode till the afternoon when things warm up and throws your jetting slightly rich. **raises hand** How about drastic changes in elevation? **raises hand**
The purpose this serves and it serves it well. You dont need a screw-stick to adjust your airscrew when needed. Reach down and set it with your fingers and get back to riding. What a novel idea!
As it comes int he mail:

It will however utilize your carbs OE airscrew spring!!!! Dont lose it or put this in without it. Unless you want to lose it and have a rather LARGE airleak...lol
I can dig it! Set at 1.25 turns out--same as my stocker was set at. Go ride!
