k&n are they worth it?

[Fazafou]

In my experience, k&n's are only worth it if you're tuning the bike to use one.

I've put them on stock bikes (and cars) before and they make no difference. Most people 'perceive' a difference due to the money they've just spent.

Also, rather than changing filters in the future, you have to clean it. It's your choice whether that's a benefit or a chore.

I personally don't fit them now and stick with standard filters.
