Ummm...is that an American Idol or a British Idol? :cheeky1:

Sorry...I couldn't help myself, but that was completely uncalled for, and you deserve a legitimate answer.

I've run K&N filters in most of my bikes, most of my life. I can believe they might change the airflow situation. I assume that this means you have filter oil now...you might want to make sure you haven't laden it with far too much.

On the older GL's you just pick up a stick at the side of the road, and adjust the idle screw, and well, there you are.

On your fuel injected baby, I have no idea. Hopefully, someone with less wit but an actual legitimate answer will amble along soon...in the mean time, I've bumped you to the top of the stack. :waving:

Thanks i just put the filter inout of the box, So it said that it had the right amount of oil on it right out of the box.I live at 5200 ft ride up to 9000 ft and cant figure out if its the thin air or it just breaths so much better that the computer cant make the change on it's own,It idle's at 1000-1050 now!!!!!!!!!!!My miles per gal has dropped of course which i would think it would be the other way around with better performance im stumped !!!

HI, MT rider. I'm from Livingston, and an old friend, Larry Ellison lives there in Bozeman. I tried to hook up with him 5 yrs ago, but they were gone on vacation. I still have a cousin in Livingston, Linda Holland.

I'm not a proponent of K&N's, but I don't know why that change would bump the idle up. You're sure you got all wiring and hoses hooked up? The drop in mileage seems to indicate something like that.

Personally, I'd go back to the oem. Very hard to beat, and they filter much better.
But, in the meantime, you might try a reset, by starting, letting the bike idle till the fans go on, then after they go back off. Shut it off. While this is going on, do not touch the throttle. Then start, and see what happens. Good luck.

I personally also wonder why the idle would change. I suspect something other than the filter at work there.

At the airflow rate requirements for an engine at idle, having a filter or no filter at all, isn't going to make any difference.

I can't imagine why you'd want to put a K&N on an 1800. They require more frequent maint. than the stock filter, and the work involved in getting to it isn't something I'd want to deal with!
My friend has an 1800, and went to change it at the specified interval, and it still looked brand new. He blew it out with air, and not much came off it. He replaced it with the new one, but plans to add a few more miles to the interval before he pulls all that tupperware again!

Maybe you could tell him that Bob Anderson said "howdy". I need to get up that way, and see him. I guess his whole family is into dirt bikes, big time. And racing bikes, of some sort. I wonder if he's retired yet? Doesn't he have a pump business, or is it just electrical?

Scott. I've been reading that some are going over 60 k on the oem, before changing, with no adverse effects.

I can believe that. The one Glenn pulled out was virtually spotless...what a stupid place for a maintenance item!!:X

When we consider all the "stuff" the public wants in a vehicle, it's amazing that air cleaner isn't even worse to get to. The whole bike is a lot of merchandise in a tight package. Wait'll you work on the interior of a late model Cat excavator or wheel loader, or pull the transmission on a small Cat crawler loader. :crying: Or, the heater core on an earlier Toronado. :X

MTN Rider - I put a K&N on my 1800 and noticed no difference. A lot of the gang here hate on K&N, and they may be right, but I'm just giving you some comparison data. It would be a huge hassle but I wouldstrip it back down to check for a sealissue in the airbox. I noticed it was really hard to get the gasket lined up right with the K&N.

I have a K&N on my 1100...but that is one heck of a lot easier to get to. It's a good filter, just not for the 1800 IMHO

I dont have an 1800 but when I put one in my 94 the idle neded to be adjusted just a tad. But I had also replaced the alternator with one thats higher rated so I needed to move it up a little. I dont know if the FI hondas have a MAF/MAS sytem and suppoedly they can be affected by the K&N. Unless the throttle will not go all the way down or the rpms stay ridiculously high I dont think I would worry about it. How much does it do up?

There might be a throttle cable adjuster that you can play with, but it will have effect all thru the range. Just a thought.

As to the K&N run it and like, they are better flow and dont require anymore moaint then a OEM and work better in dirty environments if oiled properly. Yes they can let more dirt in but then they about equal out in filter capability once a little dirty.

The K & N air filter changes the amount of air entering the fuel system as they breathe better than the more restrictive OEM filters. This means that you have created a much leaner mixture. On fuel injected models the computer needs to be remapped to bring the fuel/air mixture back to where it should be. On carbed bikes the main jet needs to be replaced with a larger one to increase the fuel in the mixture to compensate for the extra air flowing thru the system. The increased idle rpm is a result of the increased oxygen being burnt. This very lean situation will cause severe engine problems if not corrected. I had to go from a 150 main jet to a 170 main jet when I installed a K & N air filter on my Kawasaki 1500. Hope this helps!

I put a K&N air filter on my 1800 and have had no problems. When I changed out the old filter it had no dirt on it at all. I'm just wondering if it filters anything at all.?:action:

The stock Honda filter is very good. I do not plan on changing them for a different brand.:waving:
