    Had someone ask is it's possible to mount a 120cc or close on a bike. If so, frame mount or rack mount. Direct drive or centrifugal clutch. How about some ideas?

    Hi Ron -

    I am going to do some self-indulgent pompous bragging. . . . I placed a Honda GX-160 engine on my bike. Then modified the wazoo out of it. (Ever wonder what a wazoo is?)

    See if this thread in the Picture Gallery section opens for you:

    Maybe someone has gone larger, but who will admit?

    off topic but kinda not i have a 105hp gsxr750 engine in a go kart


    its all just about how much work your willing to do to make X engine mount and operate

    i have a 117hp cbr600 engine for sale with only one rad for 600$ if anyone willing to put that on a bike i would love to see.

    exactly! if you are capable, and willing to spend the time and money, anything can be built.
    A friend of mine built a bar stool (go kart) with a katana 600 engine on it.

    I've seen a video of somebody who put a 150-ish cc lawnmower engine converted to horizontal shaft on a bike as a direct-drive without a clutch. Start by pedaling, stop by braking. Simple design, and insanely fast. I have a 6.75 hp craftsman that I'm converting to horizontal (once I find a **** welder I don't have to go bankrupt for) that I may put on a cheap yard sale bike as a rack-mount. If not, its for a go-kart.

    @Doggie Daddy- stop being a ****. If you don't like it here than you can leave. The best way to get a bad rep on a forum is to rip on senior members right after you join.

    Whizzer engines are 138cc or so.
    Venice tried to talk a guy into mounting a 500cc Jawa on a bicycle.
    The guy is still alive, so I guess he didn't try it.
