Red button is an air bleed. Use it to lean the mixture at high altitude or on a hot or flooded engine..
It's plugged off on U.S. models. Seems to be a Euro thing. Where did you import it from/to?
Ah. The outline of the port is in our carb castings but isn't machined.
I'm guessing that some version somewhere is available with an adjustable air jet needle and seat, as well.
Enjoy. That may come in handy here and there.
Ill spare you the pain... no comment.I live at 4,000 feet. I'd hate to see you stuck with that ugly, oddball red button so as a gesture of international good will I propose a swap![]()

You guys not only get the good bikes that we can't get but you often get better versions of the ones that we can. lol.
Please don't tell me that it also has a 3-position, stepped needle with a clip, as well. I don't think I could handle knowing that the rest of the free world still get real carburetors.
