K&N Air Filter Queries and Doubts

[raghu123]

@prith .. thanks for the advice man really appriciate .. but its not sponge ,its type of wool those in aquarium would know it its more like scroth-brite scrubpads but it is uncompressed ,soft lite ,
i used it for a week (experiment) no sound change ,no pickup change more like stock filter ... when i opened the air box the filter really worked ,it gathered all dust upon it ..
now some DIY members can help me i think...

[juscallmelarry]

well i dont think any (DIY) people have tried this before, as i have not seen till now.
I know about the aquarium filter it should work normally..but thing is "Is it durable?" i dont think it is durable it wont last for long.

Changing filter medium wont change the sound, if you want to change the sound go for KnN filter attaching directly to your carb. , then you ll also need engine tuning..(jetting not prefer)

About jetting:- i dont think jetting is easy thing, you will find the jets in market and they dont cost even more than 50rs , but jetting can be done by any professional mech. only.

one more thing i remember i have done this on my kinetic nova long time ago, dont know it will happen now..

i simply made some small holes on my filter box that gave some sound, and re tuned the carb.
it helped in pick up but too small... but sound was some similiar to knN filter

@juscallmelarry .
Thanks for that info man
but this not really for sound change i wanted some bit of performance i.e more inflow of air .. and i used up some old exoskeleton of the filter (metal parts except filter material )..
hence u gave me an idea of hole in air box ... thinking of pearcing 2 mall holes
but any consequences , engine blocking / anything ?
and by the way do we get spare airbox lid ? just in case i dont like the sound ??

Raghu: The serious damage to the engine and carb will occur if you live in a dusty place, since ideally in this condition your mod filter will not be performing its duty as expected. In city conditions I think you can try your mod for few days and find out if it really is effective. Be sure to cover the surface of the mod filter with thin coat of 20w-40 for helping you catch more dust than the dry filter.

Upjetting, better leave it to pro's and go by their suggestion.

You are welcome mate, making hole will give more air flow thats for sure and it wont effect the engine as of course air filter is meant for what ??

it should increase your performance as more airflow and after tunning i guess more pick up.

Not so sure about spare air box, but in case you dont like it you can fill it with m-seal or any other thing. Try making holes with screw driver just heat the tip of screw driver will give you decent holes and they are also easy to fill later on.
But tunning is the important thing, it can give you pickup or hiccups

[raghu123]

well currently it is giving HICCUPS ... last tune at svc ( i do it myself but it was tuned last at the svc with full service )
well any idea why hiccups ? its more like sudden gush of air through the scilencer making a air pressure release ... lol In my language a FART

[rutvij_3400]

I think it's because of uneven afr... Try retuning it

[juscallmelarry]

you need to do a proper tuning .. i used to ride my kinetic nova with screw driver and used to ride and then tune it a bit like adjusting the petrol flow screw.. then riding then adjusting and so on till i get it perfectly tuned ..
though it look weird opening the boot after half km but it is a good way.

i told you before bad tuning will cause hiccups and sound like bullet shots

better you get it tuned else performance,mileage and top end all will be effected.

[raghu123]

how about hole in air box ... any specific place to hole up ?
well what will the sound be like ?
sorry i ask a lot to know more
and anyway what happen in high idle and low idle setting ?
i re tuned today hicups reduced only thing is i need patience so i can observe the TUNE
well i dint install the DIY filter , like as u said its risky so.........

[juscallmelarry]

well any place on the air box, try those places where dust dont go easily.. And sound is like similiar to any market filter... that kind of broom broom..
no man, this is place for helping people only..

I have pulsar 180.....i have fitted factory replacement k and n air filter. I didn't get the roaring sound.....you discussed about holes in airbox... Please guide me through

[hunkofgals]

@ raghu123

what exactly are u looking to do with the filter ?

u want that roaring sound or u just need to change the filter to after market ones to get little performance bump ?
.

ive used K&N , HP , Green cotton , and both paper n foam filters of the Honda stock ones
according to me the HP , Honda's paper are both equal and this HP filter doesn't need re jetting , just little tuning that's it
,
its gives smooth air flow and uniform acceleration , u can easily feel it !

[subashdhiv]

dude i need both performance and roaring sound.
what about free flow muffler?????????

[hunkofgals]

if u have a factory replacement K&N go for joels exhaust
the best so far
u can contact joel directly
