Are these symptons of valve problems? 09 R6

Before I fork out the cash for a valve adjustment, id like to see if the problems with my bike could be something else. My bike has 18k miles, and completely stock.

Here is a video of whats actually going on. It rides fine after 6k rpm, but before that it almost dies out when on the gas.
Thanks

No never done a clearance check. Just regular chain maintenance and oil changes. I thought valve adjustments weren't needed til around 30k.

Don't feel bad - I have 38k mi on my bike and have never done a valve clearance. Sometimes, you have to take your chances to save some moolah

24K

That's a misfire plain and simple.

Makes the engine sound harsh because of the inbalence.

Very unlikely that its valve clearance related at 18k unless the bike has had a very very hard life.

Now you need to track down the cause of the misfire...............

start by identifying which cylinder is the problem.

let it all cool down then start it up, after about a min squirt wd40 onto each downpipe in turn, the one that doesn't hiss and vapourise is the problem

Thanks Could you elaborate a little more on this? I've never done anything to my bike besides change the air filter so I don't know where to spray the WD40.

NP,
to help trace the problem you need to identify which cylinder or cylinders are missing.
As they fire they generate heat so the exhaust downpipes/headers (where it comes out of the cylinder head) get hot.
When you spray wd40 or water onto the hot pipes, it will cause a sizzle and vapourization whilst the cooler pipe/s (ie the one not firing!!) will be cooler and the wd40 or water will just coat it!!!
follow me??
this tells you which cylinder is not firing,

now check the wire and plug to that cylinder....

NP man, lmk how you get on

for what it costs I'd change the plugs out at 18k if they've never been done..

I'm assuming your not seeing a fault code on the dash btw?

Nope no fault code, everything on the dash is normal. And I just tried what you said and you're absolutely right, its a misfire. Looking at the front of the bike the outer right tube was coated in water, the other three evaporated the water instantly. You're the man! You saved me $500 Now time to fix, I can't thank you enough.

We've seen on the new R6 the valves tighten up sooner than the factory recommended interval.
There's a few different opinions on why but I put some of the blame on the seat/valve material and the lack of lubricity in ethanol.
Symptoms are hard starting when hot, rough idle/won't hold an idle, and poor low speed performance.
