How do you know when to clean K+N's ?

Hey, had a K+N fitted about a year ago (also got it dynojetted) but done very few miles since then.
However its started getting a low range flat spot again, which might mean it just needs cleaning. However like i say, ive not rode in particularly dusty or smoggy conditions often, or done many miles...

But i remember people saying they need a piss load of cleaning. So, anyone care to elucidate on how often theres needed cleaning?

Reason i ask is because ill have to get the stuff in in advance, as K+N site said this;

I'd say it'd be absolutely fine after a year with few miles in normal circumstances.

But you've got nothing to lose by cleaning it.

Don't really need gaskets unless the float bowl gaskets get mullered when you take the bowls off.

A flat spot could be dirty carbs, dirty air filter, could be anything sadly.

Don't be such a girl, just wash the filters in petrol or summat.

The pipercross foam washable filter I have I believe is supposed to be washed every 4000 miles, although I do it more like every 8000.

Hi

Given you have used it very little I would be tempted to say things have got gummed up with stale evaporating fuel. Lob a bottle of a decent fuel additive for cleaning the system up into the tank and give it a couple of decent runs, and see if the problem persists.

Also, possibly being cold at the moment compared to when it was jetted it will have leaned the mixture off a bit. Bandit was a pain in winter when the engine was cold compared to summer running.

All the best

Hi

The stuff that has been recommended to me a few times is Forti fuel additive, apparently common in Land Rover dealers.

All the best

I personally think they are a rip, they cost £40 and then you don't have a clue if they are dirty.

I've noticed zero improvement since fitting and recently went back to a paper one.

At least I can tell when its dirty or if there is another problem. Plus when I did enquire the cleaning solution was dearer than a paper filter.
