I've been knocking around the idea of building a bike for a while now...searching for parts, pros/cons of different brakes, hub vs. spoke sprocket attachment, 2 stroke/4 stroke, fenders vs. no-fenders, etc. I took a few trips to the local bike shops and asked questions; they said I was crazy and that it was a bad idea (frame weakness, components not built for the job, etc.), but frankly, I'm not so sure that they knew what they were talking about on several points. Anyway, I came up with this arrangement: the Chinese Grubee 66cc/80cc 2-stroke mated with a Micargi Falcon GTS frame? Has anyone tried it? I scaled the images as best I could but I don't really trust the sharewarepseudophotoshop program that I have. (Keep in mind that the exhaust is purely a guess. I don't know the numbers to create the expansion chamber, and this is my first attempt.) Any suggestions or advice is welcomed.
