Insane???

this sounds like a great idea

Maybe call Sportscarpat or Helmutt about a frame and wheels?

Steve.

Hey, most of them UL engines have a 10 amp lighting coil

Hey Dirt, my 2 cents ,on the next build maybe streach the frame about a foot, relocate the pedals , put the motor low and in the center of the bike then run a belt with a x twist to a pulley-roller thing and drive the wheel just below the seat post. I never did have any luck runing one of those engine without the lawn mower blade on it. To help the engine run at a slower speed you should change the timing back about 1 inch, sounds like a pain in the butt to do. Pull the flywheel and watch the top dead center and then look to see where the magnet is. I didn't think the starter rope handle would go between my fingers but think it did. On the older Brigs engines you could loose the aluminum flywheel and get one from a horizonal engine that was made out of pot metal.

I say, **** no!

dont do it.

Hey Dirt, TGISunday. It was a good idea, well a idea anyhow, my neighbor gave me a engine just like yours but I haven't tried to run it. The grandson and I started a mb project last spring but it got put on hold because of all the honey do jobs. We are making a adjustable frame with a motor in mind. For the front half we copied the OC Chopper but for the back everything including the seat post can be moved forward or back and the bottom tube can be dropped down. The seat, front neck, down tube, top tube ,pedals and angle of the front neck all stay in the same location but everything connecting them can be moved around. We ruined the first frame by welding it with stainless steel (lots of big holes). Some lawn mowers have a angle gear box that might work, I have a Treadmill electric motor that runs ok on 30 volts but its really long, wish I could mount it longways on the bike with a angle gear box. Don't give up on putting something on a bike, its something that you will never forget. The first m bike that I ever rode was one that I made myself over 50 years ago.

Well, this will definitely be a project for the future, when time and money allow for it to be done right.

Good decision I think ;-}

If you want something nimble for off-road yet be able to scoot you around at good clip on the road, Jackshaft a good mountain bike like a Giant with a 66cc.
This Giant Roam is a pretty hefty bike with all the goodies for ~$500.
