is it worth fitting a K&N????

The difference it makes is very small in the real world.

How do you work that out You only have to service your bike 3 times & its paid for itself

Assuming you change the filter at every service, correct. But you don't need to change it at every service.
My air filter is 5 years old and there's nothing wrong with it. Admitedly its only done 12,000 miles, but there's still plenty of life left in it.

Also there's the cost of re-jetting, dyno runs etc.
Why bother, it ain't gonna make much difference.

The guy asked for my opinion and I'm giving it.

Only on the carbed versions... The FI versions correct themselves to a certain degree Although I do what mine dyno'ing & Yoshi re-mapped

apparently that is completely untrue.

i always thought this, but i was told otherwise by people more knowledgable than me.

i have thought long and hard about a K&N, ive done 22k miles, in all weathers, il have a look at mine and see how bad the airbox is later.

I've been told that it IS true. Personaly, I agree, because my bike ran as well as ever with a K&N/race can, even before the remap.

i could be totally wrong, its just what i have been told... im sure someone will come along (mike1234) and put us straight shortly.

To everyone who thinks the SV has a lambda sensor... Where is it then?

I think the thous may have self-correcting FI, from some things Jorge's said on the thou forum anyway, but I bet you a pound the 650 doesn't.

Hell if I know. Don't shoot the messenger

it does correct to a degree. has to, otherwise bike would flood out at higher elevations. did a ride last year that involved a 3000 ft increase in altitude.. felt it on my carbbed 99, my buddy on his o3 said there was no difference in the way his bike ran.

REGARDLESS.. the K&N in this bike is kinda worthless except to make the person who bought it make themselves feel better. I have 26,000 miles on my stock filter from 99, and has seen all types of weather. i check it every oil change and guess what? its perfect, still shows light through the pleats and all.

i also have 6 2-strokes, and those bikes are the most sensitive to filter changes bar none.. anda K&N does flow a bit better, yes, but the main restirction is the air intake, period. Unless you plan on getting into bigger carbs or running 2 k&N pods under the tank, don't bother, its a total waste of time.

Northwind is correct. The SV1000 comes with an oxygen sensor but the SV650 does not, therefore there's no way the SV650 can have self-correcting FI, unless Suzuki have found a new way of setting up the air/fuel mix which does not require sensing how much oxygen goes into it. If you have a look at the Power Commander map for a completely stock SV650 you'll also notice that at lower revs with very little throttle it's actually set to be richer yet when the throttle is opened up further and at higher revs it set to become quite lean so even if Suzuki are using an alternative method it is obviously not very good as even the Power Commander map has to run richer as well as leaner.
