Welcome & congrats on test pass!
A good starting point would be to get a copy of the Haynes manual which has the service schedule included.
You have to remember that however good the bike appears cared for its still 15 years old and will benefit from a systematic approach.
I would start with oil, oil filter,check condition of air filter, plugs, brake fluid change & check pads/hoses/seals. Also change coolant & check condition of hoses, clips etc. Tyre condition/pressures. Chain adjustment & lube.
Known weak spots on the Fazers are the front sprocket nut-check prev posts on forum on this subject and corrosion of exhaust studs/nuts & centre stand.
Ask questions someone will have the answer!
