Topic: What can I do with this CB100 motor?

[Tugboat]

A couple of months ago I ran into a guy who had a good CB100 motor. Wrecked bike, but motor is fine - shifts, compression, etc. Anyway I picked it up for a song and I've been keeping my eyes peeled for a CB100 frame to put it in, but so far no luck. Are there other Honda frames that I could put this motor in with little-to-no modification? I might have better luck finding a 175 or something but am not sure what'll swap. Any suggestions?

I would polish it and display it on the mantle til I found a frame

Any 1969 ~ 1976 or 1977 CB, CL, SL or XL 100 or 125 will be a direct swap.

The 175 / 250 / 350 frames will accept the motor, of course, having been designed for the physically larger motor but will require some mods.

That should be enough for getting on with.

But, the polish 'n display idea sounds good, too!

make a gas powered rock tumbler for cleaning bolts!

make a go kart or mini bike with the engine

I have the same problem with a Suzuki 250 motor.It was a close call for a wheel standing lawnmower, probably wouldn't get much grass cut but could have been a load of fun.

Would you consider selling this cb100 engine?

I would put it in a Royal Enfield Flying Flea frame I have so my daughter can ride it on the vintage dirt track..

You could sell it to budlite282.

Woah, necroposting!

So what happened? Did you find your frame? Did you sell it? Did you build a minibike, gokart, lawnmower, rock tumbler, drink mixer combo?

That's funny! Actually it's just sitting here. I bought a Goldwing last fall and have been working on that. New belts, brakes, shocks, tires, water pump..... I've been keeping my eye out for a non-running 100cc Honda roller that I could just swap this over to, but so far, nada.

That seems to increase the value of a motor by a factor of 100!

It'll probably also fit a CB125S, XL125, or even an XL175.
