    When I first saw one I though it was to cool for words. I was reminded of the UK series UFO and a little of Thunderbirds are GO! and loved it. Never rode one and now I am kinda glad I didn't.

    I don't know about swapping the engine but those early K-bike engines were pretty good candidates for turbo charging. IINM, Lufty and maybe San Jose were into that technology back-in-the-day and thier suppliers is still around building Beemer turbo systems.

    Of course, with a turbo there'll be even more heat to roast you legs and private parts but who cares? :lol3

    Well, turbo technology has moved on since off the shelf kits were available, so unless you want a period piece, you'd be better off rolling your own.

    Start with replacing the stock injection with an aftermarket system such as Megasquirt. Then find an appropriately sized turbo. Build a custom exhaust and intake to make it all fit. You'd probably need intercooling - that'll need to be hidden in amongst the fairings also. Or you could use water injection to cool your intake charge instead.

    Then tuning, lots of tuning.

    If this is all do-able then you'll have to consider what the extra power is gonna do. Will the driveline and suspension handle it? What's the final drive ratio?

    All do-able and there's lots of info out there. All it takes is time and money. You'll probably end up with a slower, more expensive bike than what you could buy from the showroom, but it'd be a unique machine for sure.

    Take lots of pics and post 'em here. In the meantime, check this guy's effort:

    There's a K1100RS motor in mine, with American-spec K100-16V cams and appropriate Motronic. Someday it'll be 1200cc. I love the thing and I'll keep it until they close the lid on me.

    Plenty to think about....
    Specifically, which 1100/1200 motors to look out for at the wreckers?
    Will post report on Tassie trip.

    There are a few nice looking K1's on Ebay right now, and not much action on them. Given how cheap decent K100's are, I think even a very good K1 is hard-pressed to push much over $4k. It's seems like the rare black ones command a noticeable premium over the red or blue.

    Luftmeister's turbo kits were made by RB Racing. I have never dealt with RB, but if you go that route, you'll need to install an older oil pump (pre 1990 on most K's).

    The original motor has plenty of steam-most people just don't rev them hard enough. An aftermarket chip with a slightly higher rev limit is a nice improvement.

    The K1 is really a lot of fun, surprising plenty of bikes that are faster on paper. It has a bit of a cornering clearance problem, cured with stiffer fork springs and a better shock.

    Dr Curve claims that he use to out run Hyabusa's on his K1 IF they had a bit of head wind or hill. He claimed that Busa's would slowly be out pulling him but some wind or a hill would make them back shift to fifth and that is when he would get ahead. Personally, I think you are nuts seeing who can go better at 150mph+. Even in Texas!

    IME, ALL non-German fork chrome pits like a mofo. Showa's do it too! They all do it except for that magic German chrome.
