Valve check at 1000kms lol. Sounds like Honda wrapped it together in duct tape and glue if it needs that type of maintenance.
How does a trained ear hear a valve that's getting tight?
Typically, valves begin sitting tighter into the seats (the seats or valve face wears), thus the valve clearances get tighter. Any bike I've ever owned, the valves have never got looser, they always get tighter. Let it go too long and you'll burn the valve because it's being held slightly open when it fires.How does a valve "get tight?"
1000 km's is a post PDI inspection. Valve check at 1000 km's is just another money grab. The engine is still running on cutting oil. More harm could be done by a mechanic or apprentice opening the engine than not. If they [Honda] insist you waste this money, ask to see the valve clearances yourself. Meaning they will have to take you back and show you that the engine has been opened. Most mechanics will not crack open an engine at 1000 km's, they will run it to oil operating temp and listen for lifter noise.
What is cutting oil?
Cracking open an engine is taking the valve cover off?
Does your bike have lifters?
A thin viscosity oil.
Yes. And getting to the valve / cam covers requires removing a lot of parts.
"Lifter noise" is a term used in the trade...even for overhead cam engines.
Is cutting oil like that Mystical break in oil that I cant find any info on?
If your mechanic thinks he will damage the bike by taking the valve cover off I would question his abilities.
Is lifter noise present when there is to little clearance?
Beleive it or not, a few years back most bikes required a valve clearance check at 1000 kms. Honda clearly wants to limit its warranty liabilities for a reason.
I just do it myself, removed the fuel tank etc on my RSV4 right after buying it just to check a few things.....ofcourse I also checked the valves on one of Suzukis at about %50% of the required interval to find 25% out of spec......so ya I think its better to check them than not.
Still wondering about this low viscosity oil, cant help to think what would happen to brand new bike on a hot summer day?
When the Honda dealer checks the valves does the dealer make the money or Honda corporation?
Not really into another oil thread. Non-synthetic SAE 30 "break in" oil is what's used by some manufacturers. That's why they want it out of there at 1000 km's. The mating of surfaces has taken place as well as it's going to with hopefully no cyl glazing. These Duc guys have it all covered here:

Oil threads are generally a waste of time as no two techs, no two dyno guys, no two manufacturers will agree.
Just wondering, who's to say you checked these valve clearances properly? Would someone with a license agree with your work? There is something about "murf the backyard mechanic and Aprillia RSV4 Factory" that just doesn't sit well. Not insulting you in anyway, just hope you know what you're doing!
Sorry dont see anything about SAE 30 in that link as break in oil....maybe I missed it?
I think I checked my first valve clearances when I was a teenager......I'd check the clearances on my 450 motocross after every couple rides. Its not rocket science. Funny thing with my Aprilia dealer, he asked me to check something in the transmission so he wouldnt have too pick it up and check it himself......he doesnt have a problem with my abilities, no worries.

Thanks for telling us all about your abilities, thats fascinating. Altho I'd rather trust someone with a license and that knows what break-in oil is.
So you want an apprentice practicing on your brand new $20,000 CBR 1000 RR? Perhaps he drops the gas tank? Scratches a few fairings? Drops his cigarette in the cam cover? Strips a bolt not knowing how to use a torque wrench?
go to kahuna, best quality for your money.
