bloody big ones.
are you running open headers? is it for drag racing?
open pipes wont give you any great power increase-just lots more noise, unless you're using it for short stuff like drag racing.
you probably want to start with a main jet 3 sizes up from standard & work from there but the only way you're going to know if it works through the rev range is to muck about with needle settings & dyno the bugger.
