    I have enjoyed putting various engines on bicycles for years but only recently discovered this site. I thought I would share pics of latest completion.
    It is a OCC with two...yes, TWO 2-cycle engines coupled together via timing belt to fire 180 degrees apart. Exhaust I hand made and is a 2-into-1 that dumps into the bottom frame rail for muffling. Also hand made intake manifolds and mounted Walbro carbs. It's a total of 80cc of shear terror once I get the engine(s) started and warmed up.

    At present, I am about to complete a OCC "look alike". I have already built the frame and use an old Yamaha 100 fork and swing arm. In this frame is a Briggs (Honda clone) 6.5hp (stock) with a 22mm Mikuni carb & velocity stack. Header dumps into the bottom frame rail which is glass packed to reduce db. and give it a deep lumpy sound. I will post pics of it upon completion if anyone might care to see.

    Happy bike building to all !!! ....DynoDan

    Thanks Curt! A labor of love one might say. Fun thing is, I can fit it on the kitchen counter (where it's warm & I have good light) to tinker on! haha
    I have put engines on bikes since my childhood & each one gets more fun as
    the anticipation grows. Let the child within flourish. Happy building!! & Merry Christmas to all!! ...."dyno" Dan

    Yep I have or did when I was a kid. Started with a Monark twin when I was 15 and when the motor blue( rod bolt come off and did it in ). I built my own. Filed out and welded a big front crank sproket on the rear wheel hub left side Made a jack shaft useing carnk bearings and a piece of pipe with the small rear wheel sproket and about a 6" belt pully. 1 1/2 hp Briggs with a V-plex clutch. Reves up and pinched the belt to go. Wish they still made them. Then that winter I suped it honed the ports,bypased the govener and over reved it. Traded it for a 1930 Modle A ford. The guy to me later that the crank was flatened...........Merry Christmas to you and a happy New Year..........Curt

    Dan, welcome to MBc. That is some outstanding workmanship. You have a unique talent and a keen eye for the possibilities in a used and beaten up bike frame. I am certainly glad you decided to stop by and sign on. We are always glad to have members with your special talent. Keep the creative juices flowing.
