Air filter
« on: 20 January 2013, 10:41:42 am »
Hi
 
Just replacing my air filter. Is it worth putting in a K&N or just an ordinary one, possibly a hi flo or something similar???? Thanks.

100% K&N.


For starters a few of us on here have noticed that Hi-Flo are ill fitting.


Secondly, the K&N will be the last filter you ever buy for the bike so it's cost effective.

I've read on here a few times that the fzs runs rich as standard apparently so no need

No re-jetting but it will feel like the bike is taking a deep breath of fresh air after eating a packet of Tunes  :)

Probably on of the most effective and simplest modification you can do to the fazer to improve it.
No need to rejet as it runs rich as standard. The K&Nwill also improve the already good mid range a little, improve the mpg a little, run cleaner and give it a lovely throaty sound around the 7000rpm range.

If it was just as good, why did you have to buy another one?

i might be wrong on this so i stand to be corrected,


i read somewhere that you dont need to adjust the carbs if you put on a non-standard exaust. and you dont need to adjust if u put in a k&n filter, but if you have a non-standard exaust already on, and then put in a k&n you will have to adjust to make it worth changing these parts (only if you change both)

Many on here (including myself previously) have an aftermarket exhaust and the K&N filter and haven't needed to re-jet. That's not to say that marginally better performance couldn't be coaxed out through jetting and dyno runs, but realistically that's possibly going a bit far...

The my bike ran fine (better than standard imo) with the aftermarket exhaust and K&N :)

iam with you deadeye......re-jetting with the two improvements will make a difference but will run fine with standard jets........dyno will get it spot on but good results can be achieved at home if you have the time  :D
