You should not be needing to change the disks unless there is something wrong with them
Semmi synth for me Castrol
NGK plugs
Standard genuine yam air filter, my argument against K&N is that I had a 14 year old filter that i replaced with a new OEM one and did not notice any difference. So if a dirty old one to new one gives no difference I don't see how a K&N one would make a difference.

I bought a HiFlo air filter years ago which lasted about 3 days before i ordered a K&N.
Most likely it was a ropey one, but the bike just didn't breathe at all.
Once the new one was fitted the difference was huge.
I also did a carb balance though with a 'dirty' K&N and i had to do it again a week later after cleaning it.
So a stuffed up air filter really can alter a bikes performance, and as you say at the top end it will undoubtedly make a difference.

In my head a wet K&N filter is likely to get bunged up more quickly than a dry paper one as every single particle that comes along will stick to it where as with a paper one it tends to hit it and fall off and collect out of the way of the main air flow .
What do you think

There's a lot more air flow with a K&N

If you can, you might want to turn up your fuelling a bit too if you fit a k&n as you might be running a little lean.

Shouldn't really matter as these bikes run rich anyway, although i do reckon a carb balance will certainly smooth things out.
