When I look at the Trikesylvania thread titles this one just appears as "TecateDan and Flabios joint" The "500 effort" part does not appear. I keep expecting some sort of Cheech and Chong themed post when I open it.
Anyway, it would be so cool to see you guys cut a KX 500 pile into a zillion little rings (make sure you number them!) and TIG weld them back together into the shape you need for an in-frame pipe and then chrome it. Don't forget to purge the inside of the pipe with Argon if you do end up doing something like that.
