Does Haynes even make manuals for scooters?

One reason you may be lacking in the zip department is because for every revolution that your engine does something useful, it wastes another stroke pushing out exhaust gas, and drawing in fuel mixture. If only there was a way to overlap the process of intake/compression and power/exhaust... you could have a power stroke on every revolution.
