    Default Mikuni Carb

    As I was working on my Ural today, I came across two extra 26mm Mikuni carbs for it. Does anyone know if they would work on the VW engine? If one would be sufficient for two cylinders, I'm thinking on getting two dual intake manifolds fabricated for them. Just one idea I'm pondering. More questions will arise, I promise.. Oh yea, pictures of the build will follow too.

    IMO 26mm is pretty small, I would run both of them

    I had 4 Mikuni carb on my Yamaha Royal Star Tour Deluxe. They worked quite well for it. However, it was only an 80 square inch 4 cylinder engine.

    YMMV

    Default Mikuni Carbs

    So as I see it, I could get two additional 26mm Mikuni Carbs and put one on each cylinder or purchase two 50mm carbs and install one on each side? One per cylinder would require a bit fancier linkage but I could overcome that. One carb per side is easier to link and I know how to balance them as I do that on my Ural already.

    Four carburetors would look pretty interesting. More thinking to do. More thinking...................

    Not looking for hot rod performance, believe me. The bikes owner should not be allowed to drive ANY motor vehicle!!!! I DO NOT ride with him...

    Even tho @ 26mm a small carb I think 2 of them will be fine

    That carb is very tune able

    Be it round or flat slide

    If I remember these are CV type pre dating the HD CV carb

    The venturi changes with slide height similar to the HD CV carb

    I have seen it done.

    There is no guide to the jetting. If you ain't scared of the tuning aspect of it then go for it.

    I hope they have accelerator pumps.

    Default It should work

    Last time I posted here was before I built my trike! Been a while!

    I have a 1776 VW that I'm running a Keihin CV 40mm on ( just a single carb) and it does the job just fine.

    I think you'll be fine- a 1600 VW is 99 cu in (referring to the Square Four comment), original carb for a 1600 was a 34mm Solex. You should be just fine.

    Default Carb's

    Placed them in the box of parts I'm getting together for the trike. Box of ideas!! Since it is raining hard I'll probably take the engine apart today.
