Hi friends,I am thinking about using K&N airfilter on my Fazer. I need your help in knowing the following things before doing that.1. Which is good, K&N 1060 or 1100 or? I know there is a price diff but still I am curious to know. Also which one suits fazer more? I see that it is available in diff shapes, but I am not sure of the shape in my bike. This is all new to me, sorry if my question sounds too basic. 2. I see that people are talking about tuning the carbs, jetting, and a lot of other stuffs that need to be done along with the airfilter installation. But Do the mechanic know it all and will do it at the time of installation? Or we have to push them to do that? 3. And why some people fit it directly to the engine(carb?) while some others are fitting it under the seat of the bike? I hear that 'fit it in the box' what does that actually mean? Thank you so much for all your help :-)

these free flow air filters work by letting more air in, but more air without tuning means lean AFR which lowers power plus, increased engine temperature. Which ultimately means low engine life. That's why tuning & jetting is needed. People fit it on to the carb, because it makes a free flow filter, further free-er flowing (also means much leaner if proper tuning is not done) Experts recommend to 'fit it in box' also because air box also regulates air from crank case and supply air to secondary air supply unit. Not using air box will mean either you are letting your engine ingest dust or blocking the internal air circulation for various purpose. By the way, everything is answered some pages ago.

Hi Sandeep,

Where u did the re-jetting, and what the cost of Jet? (sorry i dont have any idea at all). I have to try that on my FZ.

cheers,
Jins

Here comes the million dollar question

I have a 20000 km old FZ-S fitted with a NGK Iridium spark plug and a K & N air filter. The k & N model is # YA1611 (got it thru a friend in US for $ 35 as it not yet launched in India..checked with the Distributor for India already). This is a dedicated one designed only for 153cc Yamaha exclusively. Neither the universal Round shaped one (RC 1060), nor the one used commonly for Pulsars(BA-2201). Pls see @ K&N YA-1611 - Performance Filters, Replacement Air Filter

I just removed the stock air filter and put the new K&N; it is designed in such a way that it is just a plug and play to the air filter box. No modifications required.

The query is: I have not done any re-jetting/re-tuning as of now. But I am feeling as if the engine (carb) requires some adjustment for optimal performance. But confused on how to do it ?

I have read somewhere (http://www.xbhp.com/talkies/motorcyc...tml#post417901

Hi there for FZ 16 U can get a K&N direct replacement air filter from planet DSG in Pune camp.
The amazing thing about is U don`t have to change anything ,simply replace the filter with new K & N with the given instructions manual.

Guys,plz suggest me a stock replacement air filter for R15 V2. I wanted to go for Simota but have not been able to contact Joel (no replies). How good is Cosworth? It is available on planetdsg but the conical one. As it's not recommended to go for the conical one in a fi bike, where can i get the non conical one of cosworth online?

[ashwinprakas]

Hmm.. Quality job done.
flat spot is lean spot. Do update on performance & mileage figures (max & min both)
P.S. How much for the bigger jets??

Thanks.
According to mileage test conducted at SVC with 400ml for petrol the result was 24.3Km's.
Me went for 130's and 140's, with 130's the output was good, but when keeping the throttle steady the bike'd surge for no reason, so went with 140 mains. Everything's been going well since, though the bike gets abit rich when hot, which I believe I took care of by setting AFR at 3.25 turns.
The jets are rebored ones, costs 250/- per piece.

Good job
I am also using Cosworth on Pulsar 180, but have removed filter box. How to clean these filter, air pressure said to be a big no on box

Thanks.
Soak in soap water and then wash with water, and then let it dry.

And yeah, these are a few pics of my plug, after running 150+kms on stock mains and around 20~25Kms on 130mains.

How to tie the battery to supports and make sure it stays there?

Make a custom clamp to keep it in place.

[Ulti Racer]

help!

I want to install conical air filter on discover 135.
I don't want to destroy the airbox. So need to remove it completely.Here comes the problem of battery. How to tie the battery to supports and make sure it stays there?

[AntiqueBlue]

Have'nt done jetting yet, here's my final output.



Now the confusion is whether to go for 130 or 140 mains. Now without upjetting the bike performs well, acceleration is spot on and theres no missing issues. Though I feel a flat spot popping up for a millisecond here and there.
