2009 R1 Can you hear if the valves need adjustment?

I recently bought an 2009 R1, but I don't know if the valves were checked or adjusted. So I'm asking if it is possible to hear the valves?

I could upload a clip.

Likely no, you can't hear them unless they are way way way out.

How many miles on the bike? I think the service interval is like 25k miles.

The sound you are probably hearing is the clutch rattle that is totally normal, as it is a slipper clutch.

Hey bud, if you want to truly know if you need a valve job, ride the bike over 120 MPH and if you see loss of power then get it done. If your bike maintains consistent power at high a$$ RPMs then your bike is fine. My bike is flashed and I ran a PC (choose one not both) since it built up carbon around the valves that cause significant power degradation after 30k miles. If your bike isn't flashed then I wouldn't worry about it. Just keep an eye on all the above.

If you haven't flashed it, I highly recommend it. You'll unleash a BEAST!

Ride safe Brother!

It has 30k miles. My max speed was around 95mph and I never go past 9k rpm, usually to about 7-8 k rpm, I'm still scared of the power. What does flashing do, increase power?
The big runs so much smoother, faster, and its more responsive overall. For example, when downshift into a corner in a stock configuration, the rear tends to slide from side to side a bit; however, when flashed the bike tends to stay in a straight-line thus allowing for quicker deceleration into corner. I believe it worth it! It's like having a brand new bike! Give it a shot and if you do not like it, flash the ECU back into stock configuration. If you were to undo the flash, you'd be the first person to prefer stock bike.

Another sign of needing to do a valve adjustment is when you start the bike from a cold start and let it idle and warm up, if it starts to act like it wants to die on you, or does actually die on you. Even if it acts like it wants to, this is a good sign your valves are off. Or when you recently did your cold start and go up to your first stop sign or light, and pull in the clutch and your bike dies. Things like this, this is a big sign that your valves need to be adjusted.
