Hey Lance, I like the color of your bike, it looks like a canary on steroids. Is that a Robin Suburu engine? I put one on my neighbor's trike and it has been bulletproof. The one I installed was around 1.6hp, I can't remember the size. I would think a 50cc version would be a strong competitor for the Honda 50. You would think someone would design one of these engines with a full magneto for lights like moped engines. How much additional cost would be involved in installing an additional coil or two? Maybe some enterprizing enthusiast will design one.
