What else is there to do at 13,500 miles?


I have an '04 Busa LE that just hit 13,500 miles today. I'm about to put on my second set of tires on it and I was just curious on if there was anything else suggested to keep this bike in top notch safe riding status. It still rides great, the only maintenance item I have done is change oil, filter, and adjust the chain. Is there anything else that I should be checking or changing at this time?
Check the chain and gears for wear. And you may want to replace the cush drives. If their worn out.
