Fitted one to my fazer to a decatted can, cant believe the difference, increase in low/mid range 8-) well worth the money!

Is your Fazer injected or carb?

I read somewhere that on injected bikes the manufacturers tend to set the fuel maps a bit lean at the lower end to get them past emission regs.......so a filter that allows better airflow can possible compensate for this.

Anyhoo.....I'm thinking of putting a PiperCross air filter in mine when I get round to servicing it.... 8-)

Its a carbed version, runs quite rich, how fazers should run tbh.


But its made a difference for the better sounds alot smoother.

Cool..... 8-)

I've just ordered a PiperCross air filter....plus all the other stuff to give the bike a good service before the spring..... :wink:

If a bike was running lean adding an air filter would make it run even more lean and could damage the bike


Majority of bikes run rich


It is always best to have a dyno run done to see how it runs

Yeah I guess so.....allowing more air to flow will weaken the mixture..... :mrgreen: Just goes to show you can't believe everything you read.... :roll:

I have been looking at the K&N air filters and was wondering if it would make the bike run to lean as i wouldn't be able to afford/see the point in remapping my bike just yet.


the K&N air filters seem like a good investment as you can clean and reuse them, a OEM air filter seems to be about half the price as the K&N one, so after 2 changes your pockets in :)

If it's a higher flow air filter, it will need more fuel than before , If bike is injected the ECU MAY be able to adjust, if it's carbed you will need to jet up and possibly raise needles and open up pilot jets. Do some plug chops or get it on a Dyno :mrgreen: :mrgreen:

although expensive, that's one advantage of the Dynojet filter (carb) packages as they supply larger main jets and even air correctors sometimes to ensure mixture is correct. Fitting those cone type 'performance' air filters to a 2 stroke without re-jetting spells death to most engines.

Ah its a injected CBR600F (02), i guess if i do some reading and find out if the bike runs lean or rich i can decide if it will have negative effects (ie if it runs rich it should be ok to fit the K&N)


Or just not bother and get a OEM filter...

checked with lads on foc u (fazers owners club) most think its best to run rich dont kno about injected cbrs tho

Posted

Ah cheers for the reply.

I think I will ether give it a good look into or just go for the stock air filter then.

You don't read if it runs rich mate, you fit new plugs or clean the existing ones, give it a hard blast along a long straight road, whip the clutch in as you cut the ignition and check the plug colours. Or stick with OEM :mrgreen:

Did a two mile ride high rpm, rolled back in cut the engine then took the photos

Reading plugs is a bit of a black art at the best of times but from what I can see from your pictures you have nothing to worry about. Let's put it another way, you certainly aren't running on the rich side, at the top end anyway.

For the sake of 20 to 30 quid I would get it on a dyno then you know for sure


The last thing you want is to hole a piston because its running lean

Running rich doesn't cause big problems like running lean does. I would have liked to see a sandy coloured ceramic around the central electrode? :mrgreen:
