Keep it clean
Do your oil changes regularly
Keep good plugs,wires,cap & rotor
Run Lucas with your oil on the next change
Don't ever let it overheat, and don't over-rev it. (top 2 causes of engine failure)
Don't waist money on splitfires and K&Ns and all that... you won't gain enough to make a noticeable difference.
Enjoy for many years to come!!!
