squiggles

I am new to the site, and came looking for a good direction in building my '06 636 into a stunt bike. I want to do a cage, handbrake, etc. while keeping cost down. Looking mainly for parkinglot stunts, but it would be nice to be able to ride highways to meets. Any suggestions would be greatly appreciated, such as brands of parts, brake setups, handle bar setups, tanks, rear seats, anything will help.
