Haha thanks Matt. Ya, my attitude on displacement has changed quite a bit from when I was younger. Now I am perfectly content with 650cc's for a "big bike".
This 70cc will be limited to putting up to the store and back, but still, there is something really pure about a motorcycle that I can lift by myself.
Right now I am debating throwing in a 120cc Lifan (Chinese Honda-clone engine). There are a lot of guys who make the swap and the engines are cheap. It would look the same - but it wouldn't be stock any more. On the other hand it would be a brand new engine and a little extra oomph for a heavy guy like me. Decisions decisions...
Anyways, I'm glad you like it!
ps - if I get it running good, the kids will likely end up riding it themselves.
