Forum: Mad Scientists Lair

This forum is for all hardcore, extremely technical information relating to production and new age trikes. Hybrids, jig construction, high level engine performance, geometry, fabrication, and engineering. Be prepared to get a blast of information that no mortal man can stand. If you can't leave anything stock, or are hungry for highly technical information applicable to trikes this is the forum for you. Igor, fetch me that protractor and metal scribe. "Yes, master!"
