As per the title, is there any gain to be had from K&N filter. Ima always a little wary of manufacturers claims

In a word No, if it combined with a free flowing exhaust then you may experience a 1-2 bhp increase but that's only due to the increase air flow, which in turn will make the bike run slightly lean so that increase will only be a certainly rpms.
If the bike is currently running slightly rich then the K&N could help improve the power but other than thats its only useful when you start having it tuned that's when you start falling down the aftermarket/modding rabbit hole,
1 day your buying a free flowing air filter and 6 months down the line your trying to decide if you want your new lightweight pistons to be forged or cnc milled aluminium .... its a slippery slope haha

Makes a noticeable difference to the FZS600, but that's a carb bike that otherwise runs rich. Not sure it works for a FZ6

Some claim noticeable gain in higher RPM (and power) range, with some loss on low revs torque. I just love and notice the sound of the open exhaust pipe.

I ve recently fitted Scorpion end cans and de-cat pipe. My understanding is that on fuel injected machines, the ecu adjusts fuel supply based on information sent to it by the O2 sensor, so aftermarker exausts/air filters are compoensated for automatically. Is that correct?

Only partially. The type of O2 sensor used on motorcycles is 'narrow band' and is only used when the bike is running at steady throttle [cruising along] to keep the bike as close to stoichiometric fuelling (14.7:1), it effectively gives a high-low output and does not tell the ECU the exact amount of fuel being burned. In all other conditions - closed throttle, under load, WOT etc - the ECU looks at the map in it's rom. That's the purpose of things like the power commander, they pull the map nodes in the direction required by the tuner. A 'wideband ' O2 sensor can be used to alter fuelling at all points and it's why you buy 'autotune' or similar devices [I dont rate them for motorcycles, as the response is too slow compared to the fuelling change rate].

Yes, they gain more of your money... :D

On it's own nothing you'd notice, if you fit a power commander you can then remap which will clean things up for you and take away the snatchy throttle response and perhaps give you a few bhp across the rev range. Total cost £420 odd or secondhand who knows a guess, about half if you can find them.
Not a popular up grade this or at least in my experience but for you it may be all your looking for, choice is yours.
