aJohn, I have over 20K on my bike, and this is what I've done so far:
600mi Break-in full service at Dealer
1,500mi First full service done by me at home
every 1,500 miles after that - oil change
every 7,500 miles - valve check/adj.
change brake pads/bleed system as pads become worn.
Oil change includes:
Changing oil AND filter
Cleaning/re-oiling air filter (original foam)
Checking coolant level
Thorough chain clean/lube
Thorough wash/wax
Valve check/adj includes:
everything an "oil change" would
adjusting valves accordingly
Checking key mounting/pivot points on the bike to make sure all bolts are still where they're supposed to be.
This is how long things last for me:
Front tire - 8,000 miles - Avon Roadrider, pretty hard touring compound.
Front brake pads - 6,000 miles - stock replacements
Rear tire - 14,000 miles - Avon Roadrider, pretty hard touring compound.
Rear brake pads - 16,000 miles - stock replacements
Sprockets - 18,000 miles and bike is pulsing, prolly 3,000 miles overdue, oops.

I think that's all the consumables, no?
Some of this might seem overkill, but my goal for the 250, on stock parts other than consumables, is 100K... We'll see if I get there, no? At the current pace, that's a total of 7.5 years, give or take a few months, 2 of which I've done, so another 5.5 years and we'll know if the 250 can do 100,000? Unless somebody else can do it...
Joe, I'm with ya on the WD40 thing... I use it to clean my chain. Just like you:
10 min ride
WD40 on chain while bike on rear stand.
- I actually let the WD40 sit for about 5 minutes.
Then I blow it out with my air compressor - wastes a lot less towels.
10 min ride
Blow it out again with the air compressor
shoot some chain-lube, and if it comes off black, repeat to step one until it's ubber clean and well lubed.
Note: I don't do this every time I lube my chain, I only do this when I do an oil change on the bike (ever 1,500mi). Other than that I simply shoot some extra lube onto the chain every 200 miles, or once a week, whichever comes last (cause I only service the moto on the weekends!
And Joe, I don't mean to be an ass, but I am kind of proud of it, the 20K was 1 year and 4 months.

(June 2008 - October 2009). My 2 year mark will prolly be closer to 30K.

At least I'm hoping...
