Query Approved

**rennycornelius** · 11-16-2008, 09:23 AM

Bored with ZMA's performance..................

i'll suggest you to not to go for the K&N,the reasons being...........

1.It won't give you the performance boost as you're thinkin...(like from 17 to 20 or so....

)

2.it'll be makin the throttle responce little crisper with the stock jets and the diff will be hardly noticable............

the best way to get most out of the K&N is to fit it by removing the entire airbox and bolt it to the carb directly..... ,and then do the jetting..........

but remember the jetting is not a childs play,it'll be trial and error when you'll get the optimum setting,and till then you wont be getting instant snap on acceleration even after installing it............

the jetting should be done by the EXPERIENCED HANDS, and dont go over in that and start by incrasing one hole in the jet at a time..........

i still suggest you to stick to the original settings and try sprocketting instead.........it's cheap and a better option.....

@topic..
k&n from my side is a no no...if you do a lot of stop and go riding.i personaly never liked the way it takes away the low end torque and transfers it towards the mid range...

**sam92** · 11-16-2008, 02:48 PM

according to me
KN + jetting results increase in performance and decrease in millege

if you have experienced mechanics then go for it

**Akshay.** · 11-16-2008, 10:19 PM

Upjetting the engine

on a serious note K&N with jetting will give you just like 2-3% gain in acceleration
Low end torque and Midrange will be better.
Mileage will go for a Toss.

I have a K&N on my zma since 35K kms now with a 140 jet.
Mileage I get now is like 27-28kmpl max

brother were telling about fitting k&n directly with the carb...
hw is it possible bro...??
earlier i was using hp filter that i used to fit directly to the carb
but about k&n it cannot be fixed because of the size it is overlarge
and could not be fixed to carb dirctly.....
that's my experience....
wht u say...???

I guess you can fix it to carb.. my classic CBZ carb is too small it is smaller than Uni's ( my mech fixed the K&N Under seat( Air Filter box) through a metal pipe to Breather tube the sound had Increased but it was all the same in all the RPM

Then with help of few freinds I removed it & fitted it direct to carb now it is good

PS - K&N Mouth is Adjustable you keep tightneing the screw & it becomes smaller by smaller

so the point is fitting of k&n directly to the carb is better then
fitting it to what u say hosepipe(that black wali tube like thing)....

is it so...????!!!!

hell yes.. Man I have done 2k kms Fitting to Hose Pipe & another 3k kms Direct to Carb & some points I have noted,

When Fitted to Hose Pipe,

1. Initial is very good but top end is Bad
2.Sound is all the same all through the RPM band

3. Mileage went for a haywire

When Direct to Carb

1. Initial is OK ok , Top end has slightly Increased

2. Sound changes according to RPM band.. It goes on Increasing as you Increase the throtttle.

3. Mileage is also better than what it was with Fittting in Hose Pipe..

U can try on your own to fit it Direct to carb. ( I did not even change the AFR setting after doing so & it is running good all the way)

@abhi
thnx bro for the information.
i too have enquired about direct fitting in carb
but acc. to some of my fellow mates fitting of
filter directly adversely affects the engine....!!
is it so...???

and what are AFR settings...???

Bro.. U fit it to Direct carb or to hose pipe the air is more obviously compared to stock.. If you have put it to Hose pipe & kept the K&N in Air Filter box it doesnt get dirty soon

, but I felt the sound is just all the same all through the Rev band which I dint like..

Coming back to Engine - K&N without Upjetting is not good for Engine that's what I have also heard from all the people but If you are happy crusing at 75-85kmph it is not going to affect much on engine atleast that's what I have heard from a SBK Mech from whom I have got fitted the K&N.

So it is all up to Individuals. whether to Upjet or Run with Rich settings on Stock jets.

AFR - Air Fuel Ratio

PS - I have done more than 5k now & My friend has done more than 17k without Upjetting & it is all good until now.

I am not saying that thier will be no Effects on engine on the longer run because even I am not sure how it is going to effect.

Ppl have got thier engine siezed with in 3k kms frm stock jet & K&N & some others have completed more than 50k with stock jets & K&N.
