Slightly OT: Thinking about Building Autocross gokart -> SCCA Rules help?
Argh! I have a fairly real chance to get a 500cc engine and sequential off a dirt bike for a "hard to turn down" price. I've always had this fantasy of building a buggy/kart that I could use to go off-roading (independent front suspension, swing arm rear, roll cage) on ATV trails and do my own 'rallycross' on a plot of private property a friend's family owns, as well as (much more realistically) using it at SCCA and other autocrosses.
So the question becomes, does anyone know of any informational resources, experiences, third-party horror stories, etc. pertaining to building a gokart with a motorcycle engine for autocross use? I'm specifically interested in tracking down exactly what construction rules/safeguards I would need to adhere to to have the greatest chance of the safety steward letting me on the autocross course?
The price is "hard to turn down" _only_ if I can actually build and run it.. I don't want to throw away that money acquiring garage clutter.
I'd really appreciate anyone who can provide/point me to an authoritative resource in a readable/comprehensible format.. _hopefully_ on the web.. but any advice will be appreciated.
