I'm considering ditching the airbox in favor of mounting a K&N pod filter, and I'm wondering if anyone else has done this mod and the effects...
I'm also wondering what pod set-up you used, specifically which "part-number"?
Anyone know of any ill effects of doing this little mod? I've never done away with the airbox on any of my bikes, so...
Thanks...

I have K&N part number RU-2970. Sounds awesome. Much louder, throatier sound from engine. I think you have to rejet though.
I vote yes - noticeable power increase and throaty sound. Just be prepared to hear it all the time. Best $25 I spent on the bike.
90GS500rehab,
Did you have to rejet?
Yep you have to rejet on the pod filters. I have them on my bike and works great. Do a search for the place that has them onsale prob just a search for the part number here will show you the link to them. It was like $25 with free shipping.

I have 150 mains, 40 pilots, and 1 washer under the needle. You don't need to go as big as 150 on the main if you have stock exhaust.
I've got a K&N question too. Went to the local shop the other day to order a new air filter (7,500 maintenance) and was startled when they said the price was over $100. So we went ahead and ordered the K&N OEM replacement part which was less than half the price. Will this be a true, drop in replacement or am I gonna have to worry about rejetting? Thanks,
jeff
If you do a search on this site there's plenty of opinions on jetting. Most agree that even a stock set-up is benefitted by going to 125 mains. This should work for the K&N replacement filter as well. I would probably go to 125's with the K&N.
You might want to try it without rejetting but definately check the plugs (see posts on the subject) to make sure the fuel mixture is not too lean.
I have the RU-2970 K&N from that usdiesel link. Best 30 bucks ever. Love the sound and there's definitely more power. Still in the process of dialing in the jetting. I wouldn't use the stock replacement K&N unless you're not wanting to go into the carbs. The stock replacement one comes with a restrictor? Why do I want someone to restrict me? :nono:
dont you need two pods for one for each carb so isnt really $60? or am i an idiot?
No, It's only one filter that covers both carbs.
I got this one:

Also rejetted.
This is a little off subjet, but here it goes anyway. It reained here last night in Milwaukee and when I tried to start my bike it only ran for 10 seconds. I have a k&n pod on it and I never would of thought that water from rain could get in it , because it is under the tank. Well it can. I checked my plugs and they have water on them. I pulled the carbs and there is water in the intake manifold. My question is how do i fix this, I am pretty sure there is water in my cylinders also.
HELP!!!!!.....

Blow dry the plugs, drain all the fuel out of the carbs using the float bowl drain screws on the bottom of the float bowls, then take the bike for a good long ride to evaporate all the water out of the motor. If this is an ongoing thing, check +/- replace your oil. I'd also check that you don't have water in your fuel tank as it sounds unlikely that enough water would get in via the air filters to do what you have described. Good luck.
Allright, I will try that. Thanks
did you bike just sit outside in the rain not covered or what happened. did you try starting it when it was raining or what? i am thinking about pod filters but i am going to have to park my bike outside with a full cover on it but i still dont want to have that happen to me. thanks.
are all your hoses connected right? specifically the drain tube that comes off the tank. the reason i say this is, the previous person who worked on my bike had that hose connected to the carb overflow tube. so when it rained, the water gathered around the gas cap, went down the tube and straight into the carbs! all i could do was laugh histerically :x
when you replace the airbox with a pod filter you also need a tiny K&N filter onteh crankcase breather, which is a hose to the airbox. Cut the hose off and attach the breather there (or directly to the crankcase, I can't remember).
p-
On the breather...Gino/DonD's bike has this super cute little PCV valve...Probably cost 99C but its a tight fit on the hose, the ring clip to hold it on the airbox also can be used and its tight. Best of all the motor can let out pressure but not suck back in...Makes for better suction and hence better running. Damn I got to get me one of those type things.
Cool.
Srinath.
so, the hose that connected to the bottom of the air box will need to have a pcv valve on it? or the one on top?
