Stumpled upon this forum last night and it really brings backs some memories. I had an FL350 when I was a kid. I had essentially turned it in to a full on racing machine, stripping off anything that was extra weight, had it bored, ported and polished, had the head shaved, racing clutch, custom exhaust the whole shebang. Back then they raced a class called "stadium ultralights" which were loosely based on the the Odyssey but were full custom frames and typically engines off a YZ or a CR. I'd love to find one of those things. Are they still around?

Yes they are still around. Sounds like your looking for a BriggsBuilt, EEE, or maybe a drakart. You can still find them for sale.

Where you from?
