welcome to the forum palmercole.
looks like youve got a great bike to work with, but a cafe conversion is more of a personal, artistic thing.
visiting the various gallery pages on the board here will expose you to tons of clever ideas. some guys here have spent years, some just days.
it all depends on where YOU want it to go.
Personally, before any mods...i'd start with a Clymer book and a shop manual for your bike.
read it, live it, own it.
Learn the basics. do a 3000mi tuneup as they outline. come here and ask questions.
once its running as it should, then get creative....
good luck and have fun with the process.
