k&n are they worth it?

[darrsi]

Im not convinced by them.
Last year I changed a 16 year old filter for a new OEM filter and noticed NO difference, so if I dont notice a difference between an old dirty one to a new one then I canot see me seeing a difference between a new oem and a new K&N.
Also everyone says that the FZS600 runs rich - but why dose it, it was built that way there must be a reason for it, and so to run it any other way would be damaging wouldnt it somehow perhaps ?

You're not convinced by something you've never tried?

Interesting.  :lol
