air box filter vs. lunchbox filter....

I want my GS to run as smooth and as much power as possible this year...

are the 2 filters very different?...I know that the lunchbox have 20% more air flow...but it's dirtier...

but if i jet it correctly...will I gain more power from the lunchbox?

how bout fuel mileage?

The Buddha · January 31, 2005, 01:30:52 AM

I dont think lunch box is dirtier than airbox K&N ... The Lunch box flows more of course but most of the flow resistance is in the airbox. The bike can run smooth either way ... just need to jet it accordingly. I say if you're getting rid of the paper or UNI filter which IMHO is the cleanest Yea a 2 way tie ... then might as well take it to the max...
Cool.

Are you running a stock or aftermarket exhaust? If you have an aftermarket, then go with the lunchbox filter.

Most anytime you increase power by increasing gas flow, you will decrease gas mileage.

Frost · January 31, 2005, 06:23:13 AM

I'll have the wileyco exhaust...

roguegeek · January 31, 2005, 09:12:17 AM

Sorry. New to all of this and need some clarification. What is a lunchbox and airbox? I know what the air filter is, but can't figure out your terminology with the other 2 things.

Dom · January 31, 2005, 09:24:58 AM

It can be confusing.

The bike comes stock with an airbox...basically a big black box that sits under the tank and has a filter that sticks into it. You can either use the stock paper air filter in the airbox or buy a K&N filter that fits in place of the stock filter in the airbox.

The other option is to remove the big black box under the tank all together and install the lunchbox filter which is a single filter that attaches directly to both carbs at once... Hmm, now that I wrote this all it occurred to me that Kerry probably has pics....Hmmm....let me see what I can dig up.

Nope - best I can do here is my K&N Stock Replacement Air Filter page. I don't have any pics of airbox-less setups. But I'm pretty sure somebody around here does.

Dom · January 31, 2005, 10:29:34 AM

Let us review all of your options:

1)Stock airbox with stock filter.

2)Stock airbox with K&N filter.

3)K&N lunchbox(ru-2970) with airbox removed.

4)K&N pods(individual filters for each carb) with airbox removed, as you will see below.

These pod filters are unusually large(for pods) and I can neither provide you their K&N part # or the # for the filters that other people have used on a GS. These are just some filters that I had for a kart that I was able to squeeze in there, but I havn't had any problems with them.

3)K&N lunchbox(ru-2970) with airbox removed.

Do you know what the K&N model number is for the filter to be used with the stock airbox?

Does anyone at all have a picture of what the lunchbox looks like compared to the airbox?

Also, is it as simple as just installing any one of these filter replacements in or is there further tweaking of other things to get your GS to run smoothly?

Dom · January 31, 2005, 11:58:13 AM

I might be mistaken, but I think you have to rejet even with K&N in the airbox... But IMHO with a WileyCo you may as well go for it and get the lunchbox or pods. You are going to have to rejet for the WileyCo anyways.

Wow, thanks...

That's actually the first thing I show people when they come over to my house for dinner..."Hey, how would you like to see my hack K&N job?...Let me just remove the tank...it'll only take 10 minutes...."

Your just jealous...

The Buddha · January 31, 2005, 12:50:08 PM

Shut up ... I have some similar too except mine aren't crumpled and bent and they aren't this long or tapered either ... Cylindrical and stright and a bit shorter ... Your's are going to be more visible I think being bent down and that far back ... Mine are barely visible with the side panels and seat on ... just get a whiff of the bottom side of these ...
Cool.

roguegeek · January 31, 2005, 12:53:06 PM

Fight! Fight! I'd actually love to see pictures of what a clean install would look like. It might make me go that was instead of the lunchbox install.

Dom · January 31, 2005, 01:46:09 PM

Sounds like Srinath is having a case of the Mondays... :lol:

Follow the link in my previous post.

I have NOT rejetted with the K&N in the airbox, but then I live up at 4800 feet where the air is a bit thinner. :dunno:

Here is an extremely related question that Dom may be able to answer:

Wileyco installed AND and K & N filter in the stock airbox.
#40 pilot, 125 main, #4 washer, and 3 turns. . . some eye of newt, and one large toad.

No?

Frost · January 31, 2005, 03:22:50 PM

can someone tell me what I should buy to rejet?

2 scenarios...

03 carb (canadian)
Wileyco slipon
K&N airbox filter

03 carb (canadian)
Wileyco slipon
K&N lunchbox filter

I would go with larger mains .. 127.5's maybe?(... but srinath is the one who can probably tell you best.)
