K&N Air Filter Queries and Doubts

[Aneesh@4GHz]

I just love the sound of my ffe. Its so calm yet bassy...

Try modding the FFE Pipe to fit exactly as the size of the pipe from engine and a good and cleaner welding.

Happy to see that PSR sir is solving so many problems here .

go to yamaha spares shop and ask for threebond paste it costs about 30rs (approx) for 15 gms , if you cant find it anywhere go for anabond paste ( white one under no circumstance buy the orange colored one) hope this helps

well thanx and how many tubes will i have to buy....? Only 1?

[Rahulbarik]

Three bond is whitish grey colored liquid gasket and costs 25/-
saw your "FFE".....I feel sorry for you since you have been taken for a ride..whoever made and welded it had done a sloppy job...a FFE will reduce FE by a small margin , but what you have posted only shows that it is not suited for your engine..The exhaust tube from your bike is large and the FFE is smaller and the welding is very crude.


..there is no smooth flow of exhaust tube lines, then how do you expect smooth flow of hot gases "..
Remove it ASAP and save your engine...

Did your "Tuner" tune your engine for performance.?

yes he did tune the engine for performance...... i am getting a feeling like someone is pulling my bike from behind..... And it feels like the bike is asking for more fuel.... I think i have to remove the ffe. neways i'll sell this bike in december..... will releasing some more fuel help....? I just love the sound of my ffe. Its so calm yet bassy... and regarding that gasket part...i thought it will cost 300-400 bucks. will give it a try.... And try tuning the afr once more... Will have to find the perfect afr... And thnx psr sir.... Will give updates once the mod is done and sir whats that thing above the tube?

[psr]

wow sir that was a nice explanation..... got my answer. And regarding the three bond liquid gasket...., what do i tell the shopkeeper to give. Three bond liquid gasket....? How much does it cost sir....? And how does this thing actually look....? And thanx a lot for helping me out.... M a new biker so i dont know much about engines. Want to learn all these. And 1 mre question. I fitted a freeflow 3 days back, and now my performance have dropped a lot, and mileage became around 15.... what might be the problem? I am not at all ripping my bike...i am riding between 35-50. Still low mileage. Plz help me. These are the pics of my ffe

Vibration in bike can be mechanical and Ignition induced....Whenever the carburetor is away from the air filter or from engine inlet , a slightly long rubber or metal tube connects it to the appropriate connection.....
The engine is first of all a thermal machine converting at best 30% of combustion energy to motive power...
It is also an Air pump..imagine the inlet valve opening and air fuel mix rushing into chamber due to suction...now when the valve closes the inrush of the AF mix continues due to momentum and successive waves collide and return back to air filter,and now the inlet valve opens and present suction to the air filter...the returning wave and incoming wave due to suction both collide in the inlet manifold to create standing waves and results in very poor filling of the chamber...this collision creates what is called a resonance and is not good for Volumetric efficiency of engine.So either the manifold has to be short or resonators which will absorb the resonant energy must be fitted to manifold,for efficient AF mix fill in the bore.
When you had a short air path you had avoided the resonance,and got it when you fitted a tube...
The removal of Gasket from bottom of bore is recommended since pressure levels are low and leaks are less likely to happen. You must apply THREE BOND liquid Gasket to seal the surface in place of the gasket...
This means removing the top head and bore ....Alternately the top Gasket between the Head and Bore can be made thin or removed and three bond applied.
If you are removing the top head gasket then care must be taken to apply the three bond liquid gasket and tightening the nuts properly so that no leak happens.
You are not bugging me,and happy to share what little I know..

actually my tvs flame vibrates like hell even on 35 kmph. I fitted the k&n only to make it smooth and my bike did run smooth after that. And also a large bump in mileage i noticed.... This i got when the filter was fitted directly to the carburrator... And when i fitted the filter with my hose pipe, my bike was not even crossing 50 in top gear. What made this difference sir? There surely is something related to the amount of air entering.... I am always eager to know this.... And sir how will i remove my gasket and from where? And what to do after a remove the gasket? and sorry sir for bugging you so much

It can be done on a P180 as well as TVS flame...but not on any bike with 10:1 or higher compression or with LC..
K&N will increase inlet AIR noise..you will not get any horse power increase.Eventually it will lead to more dust getting inside the bore and ruining the engine over a period of time.If you want go for a bigger Paper filter and do some mods to fit it without air leaks...It will last longer without dust getting inside...

Can this be done on a P180UG3?

can this be done on my tvs flame? How to do it.....? And sir can you plz tell me if fitting a k&n with hose pipe increases the amount of air than fitting the k&n directly to the carburator.... Because my bike was not pulling properly after using the hose pipe. Plz make me understnd the theory

In Karizma the gasket below the bore ie., part no 2 can be removed ,and Liquid Gasket "THREE BOND" by name can be applied in it's place,to bump up the compression and hence a little bit of power(0.8 to 1 bhp).This will also increase the Fuel efficiency.
Removing the top Head Gasket may lead to compression leaks since the combustion takes place on top,and the pressure and heat levels are much more than under the bore.
In most engine with bottom gasket this can be done for marginal increase in compression and FE,since most of the gaskets are 0.5mm or less.
This should not be done in Engines with 10:1 or higher compression as it will lead to pre-ignition and detonation.

[Aneesh@4GHz]

ive asked my mechanic about all this
he said we can remove the metal thing
and he said he will use that THREE BONd

ill update u guys after i get the mod done

thanks a lot
@ aneesh and PSR

Cool bro. Waiting for feedback from you and remember, Do not save three bond and apply very little ,it will leads to oil leak,So apply it as necessary,not more not less.

IS this a tongue smiley? I use this as a smiley for thinking.




Yes



The distance between the piston top and the head will be reduced by 0.5mm and will results in increased compression ,which gives us the bump in performance.





Yes,Its the Liquid gasket.



Have a look at this pic,Karizma's cylinder and gasket.




Don't know about this,PSR ji Help!

where to find this liquid gasket? What shud i tell the shopkeeper? Whats the price?
