    The goal concerning the single carb was simplicity. As far as the above is concerned, just curiosity.

    Thats another item that has been successfully applied to Airheads. Once again, there were several people who transplanted VW injector systems into Airheads in the late 80's/early 90's.

    I would think that it would be much easier today but that stuff is over my head. I'm doing well to take care of what I have!

    Now your talking!
    I don't think it would be easy, but supercharging would be a good way to get some healthy power out of an Airhead. Turbocharging works, but is not the best way to go with a twin.
    I would look into an intercooler, and water/alcohol injection as Airheads are already detonation prone already.
    Now you just have to figure where to mount it, and how to drive it!

    OK gotcha, well the stock cv carb is pretty simple but I see where you are going. I had a Judson Super Charger on my VW for a while, did not gain much power but it looked cool.

    I have been curious about this for some time. I have two airheads that are running perfectly well, so maybe it's time to 'break' one of them. It turns out that one of the guys in my glider club has a dyno, so some figures would be available. I would expect, and accept, some loss of power. The icing issue was truly significant on the old VW's, and would likely also be a big issue on the airhead. I think it might be easier to feed warmed air to the air filter box (like aircraft)than to do it like a VW.

    Less moving parts, less wear items, EFI seems simpler to me.

    Well that would make sense and if we are going to be sensible then leaving the stock CV's would be the best option. I was just tossing out a really complicated idea that would cost a lot of $$ and make little power, kind of like adapting a single carb.

    Yeah, they call it a K bike.
    Same basic system as the aircooled VWs

    Very true ... but if you convert to the one-into-two throttle cables, that will be the last time the carbs need balancing until they're removed for rebuilding.

    That hasn't been my experience.... this is with five airheads and 20-ish years. BUT, I could be doing something wrong :lol3

    Yeah, I was kind of wondering if he had a line on magic throttle cables.

    :dunno

    Yeah, and you can buy a set from me for only $149.95 + SH.

    My uncle came up with the design and passed it on to me. They look and install exactly like the BMW parts right down to the markings on the cables but mine are "set and forget forever" and if they do go out, just rebalance the carbs and they're set forever again!

    Come and get em! :evil
