What I want to know is why did they tune the fazer to run rich, there must of been a good reason, so by fitting a K&N are you not "braking" the tuning the factory made.
I've only just changed my filter at 16,000 miles to another OEM one, and didn't notice any difference in performance,
So far I only read darrsi has seen a difference in performance with the K&N filter has anyone else seen a difference?.
My brain cogs are thinking if I saw no difference from a 16000k - 15 year old one to new oem then why would I expect to see a difference from an original to a K&N, I fear that any difference felt is physiological.
The K&N isn't as filtered as other brands, it literally lets more air in and these bikes seem to love it.
As to why they were originally rich, who knows, but the fact is they work really well with only positive side effects.
