    These spares are for the Mikuni “VM” type (round slide, aluminum-bodied, spigot mount, “GP”) carbs as shown, right, except as noted (* = radial slide). The prices are current as of October 2005, but will change with time. Limited quantities available these items; the prices shown are for parts in stock only.
    You must know what model you have, and which parts fit - parts are not returnable. If the exact size you requested is not available, we will send the next richer size unless you specify “only”, etc. Some brass parts (jets, needle jets, etc.) have been removed from carburetors and are therefore “used”, but are still in like-new condition as to their metering accuracy. If not acceptable, please specify “new only” when ordering.
    These carburetors and parts are

NOT RETURNABLE

. If the part you are looking for does not appear on this page, I can’t supply it.
    For new Mikuni carburetors, click here to go to KNS Cycle: 

    Slides (throttle valves) have either left or right side idle screws (as seen look- ing down the air horn), and 1 of 3 different guide pin groove widths:
2.05mm = .081”, 2.60mm = .102”, 3.05mm = .120”.
    Shown here in the diagram, right, is a right side idle model, with the slide’s guide pin groove on the left.
    The slides shown below are exactly as described.

Due to the high fee that PayPal charges me, there is now a service charge of approximately 3% (US customers) or 4% (Canadian & foreign customers) on PayPal payments. This is less than it costs me to collect this money, and still less expensive & more convenient than your bank. Please add this to your total for items and postage, and sales tax for delivery to New York.
