Oil changes at 600 miles, 4000 miles, and then every 3500 miles AFAIK. Valve check at 15,000 miles. Check spark plugs on every other oil change, but definatly change every third oil change. Air filter every third oil change I think (about 12,000 miles). Keep an eye on the air filter though...my dad found his (K6) got quite dirty, more so than my SV air filter even though I did many more miles than him.
I think you'll be looking at spark plugs and an oil (and oil filter) change at 7500 miles
