What is the largest cc engine that you know will fit on a bike.

[Al.Fisherman]

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?

Thanks,
MikeJ

Now I really feel bad. . . . I have already been humiliated by another builder:

Leave it to the younger guys to come up with something radically new.

Note we both use the same upgrade parts and the same parts supplier.

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.
