    idle mixture screws

    While looking at Partszilla I don't see idle mixture screws or maybe I didn't look hard enough but are they available? Lots of parts I thought you could buy are unavailable. Are these genuine Mikuni? Just curious.

    The "newer" mixture screws can be hard to find. The good news is even the ones in the K&L kits work well. Jets, seat and needle are the only parts that MUST be genuine Mikuni.

      Try Partshark--I just got a set from them, though they were backordered and took a while to come in.

        Great will do. I like to have things on hand just in case.

          ALWAYS compare kit mix screws to your originals, often times they are not exact, shoot for exact.
          If new ones are a bit short for example, you will be too rich at idle and not able to adjust it leaner
