    Hi everyone, first time posting here so don’t even know if this in the right place.
    Here’s the deal, I recently found some motorcycle parts in the shed of a house I recently bought. Among those parts there are some Krauser 4 valve heads. From the little research I have done it seems like these are quite rare and interesting. Not really sure what I have hear, or if it has any sort of value. If someone could give me any advice on what they might be worth or what to do with them it would be greatly appreciated. Thank you!

    Welcome to the asylum, and this is the right place!

    Krauser 4 valve heads are desirable to some. A PITA oddball to others. Given that you "found" these, I am imagining there is no use history, or other provenance with them? I see there are some cylinders associated with them. Pistons too?

    It looks like they have been used some, and yes they have pistons.

    Jim, you entertaining a move to 4 valves rather than turbo - or planning to combine both for a real structural integrity test?

    Talk to John Olive in Aussie. He’s done the turbo, 4 valves and fuel injection.

    I can't afford them if they really bring that kind of coin, @Kiwiabbo. Perhaps I'll find a set in a shed someday.

    At a BMWMOA National Rally, I saw a bike with Luftmeister Turbo, 1100cc kit, and Krauser heads. It leaked oil everywhere, but it must have gone like hell, at least for a time.

    Luftmiester kits developed and pumped a lot of heat. For an entertaining read on the history and a lot of angst, check out “RB Racing” who actually built/ build kits ( if you want to plug in the whole thing for $$ rather than build one)

    Yeah they pretty dirty on the whole luftmeiser thing. Think they would rather you never mentioned it.

    Krauser heads AND fuel injection. This bike will be for sale shortly in Australia minus the FI but with new Dell'orto's, if anyone is interested.

    PS: This bike was built and is owned by Ray Peake, I only take it upon myself to show his creations off.

    At least you recognized they weren't junk, and didn't just toss them on the curb for the scrappers.
