However for people like me, who have read and reread jetting threads, but still am clueless how to tune carbs,...  it sounds like an easy way around the jetting issue. I can turn a wrench just like the next guy but it is hard for me to understand the way carburetors are adjusted and how to figure out what adjustments to make when I'm out riding. If that carb can adjust itself, I may think about getting one for my 250 for shear convenience once I start rebuilding it. Post up a pic please.

The top knob is the rich / lean adjustment on the needle, the side knob is the idle adjustment, and of course there's the choke. Again, it's not ALL about no more jetting, but that did direct us towards this instead of a Keihin AirStryker carb which probably would have ran $275 anyway.
