I'm new to the board.  Hi!  I ride a 1992 gs500e and live in Seattle.  This is an awesome site, the kind that really makes me appreciate the internet and wonder how those poor bastards 15-20 years ago ever got anything accomplished... anything that was cool at least. :0)

My question:  I read on www.bikepower.net, a Dutch site in English, that the k&n filter created excessive noise, so much that he needed ear plugs for the long hauls.

QuoteI must say there are also a few disadvantages. First of all the air filter element. It makes a lot of noise. I use earplugs to protect my ears on long rides.

I don't see how this is possible.  Maybe he translated his thoughts wrong?  Either way, his English is a million times better than my Dutch.

Does the K&N lunchbox make excessive noise?  I would like to reap the rewards of having one but I don't like the noise idea.

Thanks in advance, Dom

Edited by scratch to remove the "amp;" from "K&N"

If  you're talking about the K&N RU-(somethingsomething) then...  Well, it is louder.  But who doesn't like some noise?

I think it's just that it's sitting right underneath you.  I had a buddy watch me drag race after I installed it and afterwards I said "didn't it sound cool?!?!?" and he just looked at me...  Like... "I couldn't hear a thing dude".

It's louder but I don't think it's offensive or anything

I wouldnt think it would be louder then the wind noise you would get from higher speeds.  Maybe Joris will chime in and clarify up a little more.

The K&N lunchbox is the single filter that has openings that clamp onto the throat flange off each carb.  AKA k&n# RU-2970 Kind of looks like this, well exaactly like this:


I guess the airbox has a muffling effect, eh?  

I don't mind extra noise for short hops, it's just those long trips where I wonder if the noise will start to wear on me.

Btw, I have already removed the airbox, and didn't have the lunchbox but I did have two separate k&n filters laying around the shop that just happened to have a 2-3/8" mouth and fit on the carbs perfectly.  Think it will make tuning any harder?  Guess I won't be able to rely 100% on other peoples recommendations if I start throwing variables into the equation eh?  Wish me luck.

yes its LOUD.

I rode it 3 miles 2 weekends ago. I plan to try take it out tommorow (im in LA right now). But from what i remember it is loud, and sounds oh so glorious. It definately has a nice throaty sound when you hit teh gas. Its quiet when your cruising (quiet is relative when you open the throttle a bit).

I will see if I can record the sound tommorow on my Canon A70.

I've ridden my stock filter/airbox/drilled stock pipe bike back to back with my buddy's pod filter/no airbox/Jardine full exhaust (Daniely) and it definitely is noticeable (the filter sucking effect) even with the louder exhaust.  It's a great sound though, in my opinion!!

I can't hear the K&N anymore over my OPEN SUPERTRAPP!   :lol:

When i rode MK1inCali's bike (Tony) i couldn't hear the exhaust or anything hardly at all. I got back on mine, and its LOUD, at a stop when you rev it, a split second before the exhaust sound comes into play, you can hear the airbox sucking in air. Oh its wonderful. Its taken some time to adjust, but it sounds like its revving to hell and back with the louder exhaust and filter, when in reality im sittin steady at like 5k. Gettin much more tolerable now for sure though.

What about sucking in water? I'm worried that without the stock airbox, the intake could pull in water easier. I live and ride in a very wet climate, so this would deter me from getting the lunchbox filter. Anyone know, either from experience or just from hearing about it?

Water ... will not hurt your motor .. unless it was in the gas ... in large quantity ... they obviously it wont burn ... water wont hurt and you wont get too much with the air filter anyway ... K&N is pretty good at keeping water to a minimum ... foam or paper will be worse ... much worse.
Cool.

That's all I needed to know; my order has been submitted. Thank you much.

so I see you put a little filter on the breather hose that goes into the valve cover. what filter did you use?  what have others done with this hose?

  Here we go, wrecent.  making it hard again. Just go to Autozone or Advanced and grab one of the breather filters that they have for 10 bucks. I have the same setup except i have the hose going into the filter. Works the same to me

[f

The one i have is an apc filter. I pinched the hose just abeit and  slid it right in. There is no binding in the hose at all.

Ran the bike briefly without any filter, when working on my carbs. The engine had a deep burbling sound, it was definatly louder and more appealing

Some water wont hurt the engine as Srinath said.  If you regularly ride in the rain though, I'd imagine you'd need to oil the filter more often.  I've heard the water can cause some of the oil to wash off.

how's the throttle response with a lunchbox?
