question about the K&N air filter on a GS500F

[sprint_9]

They are different carbs I believe so the numbers may not be doing the same thing in each carb.  With my older style carbs and the amount of air and the ease of the flow of that air in and out of the engine more of it was availible for use, therefore you have to richin up to meet the demand of all the extra air so you have a good mix of air particles and fuel

[davipu]

first of all a dynojet kit is a bunch of mikuni jets repackaged, with a whole bunch of worthless extra parts that you are paying for and don't need.  the factorypro is the same way only with knockoff jets.  

stock the bike is that lean for emmision reasons that going up three or four sizes is nessaccary to get it to run good.

[mjm]

Ohhhhhhhhh. 2.5 = one size.... all the same. 150 is absurdly large.

150 is just about right for a street bike with pods and exhaust - it is where most of us end up when we do jetting by trial and error - and that has been the number ever since 1989 -

There are those who will swear by one size smaller - and those who are using the dynojet needles will use much smaller jets (the thinner needle in their kit lets more fuel flow through the emulsion tube than the larger stock needle - so smaller jet works)

Still... 150 seems absurd. My father does a DIY jetting on his FZ1 with exhaust and pod, and he's running 2 125s and 2 127s. Maybe because of that it seems crazy...

Different bikes with different carbs.

[mountindewGS]

No, he has a ( F model  ) like mine. What jet kit would I use if I get a K&N Lunchbox and not do anything else like exhaust or anything.

[mountindewGS]

What exactly is a K&N Lunchbox or and pod? and what the diffent between a normel K&N and a K&N lunchbox or and pod?

[sprint_9]

Lunchbox is one that goes inside the airbox, basically a stock replacement, a pod is a round filter the completly replaces the air box, it is basically a box filter that connencts to the carb, alot less restriction.

[davipu]

normal = "drop in" ; replaces the stock filter, you still have the airbox.
"lunchbox" ; one single filter that goes over both carbs.
"pods" two filters one for each carb.

[sprint_9]

Ahh, ic, well that makes more sense then mine, technically a lunch box is one big pod, but oh well. :dunno:

[mountindewGS]

Alright so Iv'e been looking at the Lunchbox K&N air filter, How much of a gain in horsepower and torque if any? Do you rejet the bike or not?

Im a big fan of the pods two filters style, How hard is it to install the pod air filter on a GS500? I know you've got to get a good amount of horsepower and torque out of the pods right? and I take it your have to rejet the bike after installing the pods?

What is the part number of the K&N pod? What is the part number of the K&N lunchbox?

Which one the best pod or lunchbox do to if your only going to modified the air box?

[davipu]

ok, lunchbox or pods for hp/ torque increases of 5-10 hp you will have to rejet with a exaust.    to put a LB/pods on without a exaust yes you will still have to rejet it and it will run really crappy.   if you don't want to remove the airbox get the k&n drop in. with a rejet and the drop in you will get a 2-3 hp increase. but the bike will run smooth, and will not be affected by altidude or rain.  time it takes to swap filters, about 15 minutes max.




stock replacement "drop in"  part number is SU-5589
lunchbox part number is RU- 2970

K&N does not list the pods as a option.

Sent you a PM

[mountindewGS]

Alright,
Im looking more into  the K&N Lunchbox now. Whats the jetting if your going to do the K&N Lunchbox on a 04 GS500F? I was just looking at the D.I.Y for changeing the jet kit and it look like you have to take the air box and the carbs off, that look alittle to much for me so I was wonder could you take it to the dealer and they do it?

[davipu]

they can do anything, they just charge 65 a hour to do it
