I was concerned about this alot when I got my RC.. I had a Ducati that I let got 10K between adjustments and it sounded sooo bad.. From what i learned on here alot of guys are going 25k plus without and adjustment.. Start saving and listen you your bike.. You'll know when its time to park it til you have the money.. Or you can do it yourself..

These bikes have pretty good metal in the valve train.
If you ride your bike reasonably, then of course you can slide on the valve checks a bit.
They recommend checking every 16K miles, and most of the time they don't need re-shimming.
So you can probably slide for a while while you're saving for a service.
I don't recommend going a huge amount of miles between checks.
Having valves with clearances too tight or too loose is not a good thing.

As a side note, I just picked up an '08 FZ1 and the valves only need checking every 26K miles.
Amazing how well built engines are these days.

I also am in the range of a valve adjustment!

So what signs and sounds should we be looking for when out for a cruise?

I've noticed a little bit of a power loss in the beast from 8-9.5k, but not sure if its in need of a custom map with the Yosh's? Or a valve adjustment? Powercommander website map might not be right for my bike, so might have to get the service manual out. And I ride it pretty hard all the time, even when off the track.
What you guys think?

Take your time, do it yourself. Then you have learned a skill that will stay with you forever....and you won't have to worry if the dealer screwed up the job or not.

A lot of RC owners I've talked to say their first valve check was a waste of $$! They all said they were within specs the first go round! They said they were going to have them checked every 32k miles from that point on! Jus sayin`

Had mine checked at 25K miles when I bought it. Only one shim was slightly out.
Had it checked again at 36K miles and no shims needed.
This time (at 47K miles) I'll be checking it since I've bought the shim kit, feeler gauges, and micrometer to do the job.

Procycle.
Locate the 9.48mm shim kit.

Download the service manual from this site:
http://www.rc51.info/index.php?page=service

Then read the section on valve adjustment.
It's not difficult, but you will need to have the proper tools to accomplish it.
