You should be so proud of yourself right now. To me, this is the pinnacle of DIY home-built motorized bicycling. That engine is truly a work of art that I can't stop looking at. Congratulations on both this engine and the single cylinder you already built. Top notch craftsmanship!
butch I have been fine tuning the engine with some success. Its still not running like I want it to. I don't have much time to work on it this time of the year.i hope to get the frame built this winter. When I get started building again I will start posting again.
Tom, that's something to be proud of! I wish I had the machinery to build things. I followed something similar and got super jealous of his work. Maybe you could machine a little rotary for a motorcycle or a bike?
