Boro Jake Posted January 6, 2012 Share Posted January 6, 2012 Fitted one to my fazer to a decatted can, cant believe the difference, increase in low/mid range well worth the money! Quote Link to comment Share on other sites More sharing options...
Tango Posted January 7, 2012 Share Posted January 7, 2012 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....

Boro Jake Posted January 7, 2012 Author Share Posted January 7, 2012 Its a carbed version, runs quite rich, how fazers should run tbh. But its made a difference for the better sounds alot smoother. Quote Link to comment Share on other sites More sharing options...
Tango Posted January 7, 2012 Share Posted January 7, 2012 Cool..... I've just ordered a PiperCross air filter....plus all the other stuff to give the bike a good service before the spring..... Quote Link to comment Share on other sites More sharing options...
Stu Posted January 7, 2012 Share Posted January 7, 2012 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 Quote Link to comment Share on other sites More sharing options...

Just goes to show you can't believe everything you read.... Quote Link to comment Share on other sites More sharing options...
Sigil Posted January 7, 2012 Share Posted January 7, 2012 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 Quote Link to comment Share on other sites More sharing options...
megawatt Posted January 7, 2012 Share Posted January 7, 2012 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 Quote Link to comment Share on other sites More sharing options...
giocast Posted January 7, 2012 Share Posted January 7, 2012 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. Quote Link to comment Share on other sites More sharing options...

Do some plug chops or get it on a Dyno 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...

Boro Jake Posted January 7, 2012 Author Share Posted January 7, 2012 checked with lads on foc u (fazers owners club) most think its best to run rich dont kno about injected cbrs tho Quote Link to comment Share on other sites More sharing options...
Sigil Posted January 7, 2012 Share Posted January 7, 2012 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. Quote Link to comment Share on other sites More sharing options...
megawatt Posted January 7, 2012 Share Posted January 7, 2012 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 Quote Link to comment Share on other sites More sharing options...
Sigil Posted January 7, 2012 Share Posted January 7, 2012 hmmm i think i will just stick with the OEM ones for now then lol Quote Link to comment Share on other sites More sharing options...

giocast Posted January 7, 2012 Share Posted January 7, 2012 (edited) 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. Edited January 7, 2012 by giocast Quote Link to comment Share on other sites More sharing options...
Stu Posted January 7, 2012 Share Posted January 7, 2012 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 Quote Link to comment Share on other sites More sharing options...
megawatt Posted January 7, 2012 Share Posted January 7, 2012 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? Quote Link to comment Share on other sites More sharing options...
