I have a 2008 R6S that I bought in 2015 from a used dealer (stupid rookie mistake, but what's done is done). Biggest things to check and change are as follow (learn from my experience overhauling this bike over the last year):
- Tires. Make sure they still have plenty of good tread on them (look for the tread markers). Also make sure to inspect for cold or hot tears. Hot tears will looks like long perpendicular streaks coming from the sidewall toward the center, whereas cold tears will lok similar to a horsehoe shape. Both of these are bad and will quickly destroy a good tire (something you don't want happening in the middle of a corner).
- Valve adjustment and timing. You're pretty high in the recommended interval, and it's an older bike, so checking to make sure that this is still within spec will ensure you don't throw a rod at some point in the near future.
- Adjust suspension. Many new riders go in and just crank away on their suspension until it sags the way they think is correct. Unfortunately, they don't usually adjust it correctly which adds a lot of unnecessary pressure to your forks and seals (which frequently blow on sportbikes with bad adjustments). There are some great how-to videos on Youtube for this.
- With the dark oil, I would say the previous never changed much in the way of fluids. Do this! I recommend changing all your main fluids (coolant, brakes, etc.). You can change your fork fluid if you want, but if the suspension sits well after proper adjustment (and doesn't seem to 'stick') to your weight and riding style, you shouldn't have to worry too much until 35-40k (but check the service manual to make sure the interval)
- The chain is always a good piece to replace on an old used bike, but when you do, make sure to inspect your sprockets as well. If the teeth are worn or there is build up on the sprocket, you can quickly wear out a brand new chain.
- Brake pads. These last a substantial amount of time on sportbikes as they are designed for some pretty high levels of wear and tear (high speed stopping). Once you replace the brake fluid, take it out for a ride and give it some good squeezes. If they seem soft, or you hear some squealing when you jam them, it is probably time to replace them.
Overall, these are just your basic used used bike adjustments. Make sure to compare what I am saying to the service manual's suggested intervals, and when in doubt, call a licensed dealership to get their mechanic's opinion.
