That Spitz engine looks suspiciously similar in design and implementation to the Solex machines... incidentally is the large round thing on the bottom of the engine the exhaust?

I am *trying* to get hold of a boost bottle for my bike - I can find it online, but do you think I can buy the thing? *pout* ... any ideas on how to get one out of the states (its a tanaka part specific to the 32cc engine..)

How fast does the bike go with that engine set up? have you tried the nitro version yet - like the guy who got a velosolex to do 45mph!
