In your opinion, what do you consider the most important maintenance items/procedures that you do to ensure the continuing road worthiness and onging performance of our bike? Feel free to list them in order, and feel free to add a 6th, 7th, etc. Thanks in advance for your input.

Follow the maintenance schedule in the manual.

For me it's
(1) air pressure in the tires, (once a week or more)
(2) oil and filter changes (every 4K)
(3) chain adjust and lube (when needed)
(4) brakes (when needed but looks like every 20K)
(5) air cleaner and spark plugs (every 25K)
(6) valve adj (haven't decided on interval yet ..but I haven't done it yet at 18,000 mi)
(7) lube clutch pivot (when needed)
(8) brake fluid replacement (every couple of years)
(9) Battery (when needed)
