Don't do it. Buy a new set of decent Mikuni flat slides!

The build quality is terible, and the Chinese carbs that I sonic cleaned, turned a very dirty, blackish swirly gray.
I would not trust them with any of my engines.

I was given a set of these and realized they are airstrikers with the fins polished out of the Venturi, you would think no big deal but apparently it is because where the nozzle protrudes into the Venturi it needs a hood, well that was messed up too and it had some wild jetting needed, we spent a 1/2 day on the Dyno and could not get them to perform, it had stripped screw and something else, I said that's enough of that, I stand with Rory

Just not worth the risk and that goes for genuine jets, needles etc

If you make the cheap attempt, at least use the real Mikuni jets. The Chinese stuff has no tolerances required for the manufacturing. They reverse engineer.
Your jetting will cost more then the carbs, and they still may not run right, ever.
