I haven't had one so can't give you specifics. But Procircut and probably boysen will have guides or alterations from standard that is a good place to start from.

Here http://www.procircuit.com/jettingspecs.htm is the jetting page and
here is a vid of How to install a full kit http://www.procircuit.com/rev2PLUStext.html. Mind you it won't apply to your early model carb.
Bosen will probaly have some stuff as well but I'll let you do the homework on that. Google is your friend!!
The fine tuning is done by plug colour and experimentation during your rides.
