OK, just a few thoughts.
Use the best quality fuel -super unleaded as the bike will run better and give better fuel economy.
Tyres, I have only tried Michelin PR2, PR4 and road 5's. All gave me 10 to 12k miles, Road 5s seem to be best in the wet but there are other makes which are just as good.
Oil, most semi synthetics are good, have used motul, ipone and shell.
Oil filters, I normally fit a hi flo hf204, i stay away from K&N especially the ones with the nut on the top.
Yes the headlights are crap, best conversion is to fit the Sport headlights
Best idea Is to read the posts in the stickies, loads of great info and guides in there..
