K1200GT Aif Filter Service

So, today I was doing the 12K service on my 2008 K1200GT. This bike doesn't get the kind of use I planned once I bought my R1200GSA for adventure riding.

Two or three years ago I did the 6K miles service, and last year I put new Michelin PR3's on at 10K miles.

I bought the bike with 1700 miles, previous owner was in Arizona, didn't ride it much at all. He or the original owner farkled the bike nicely.

So, oil and filter change, check.

Air filter change - I removed the side panel and pulled the filter and found one of these K&N air filters. It was black and oily and covered with grit and bugs. Glad to see that stuff didn't get into the engine. I suppose I can wash it with solvent (?) and put it back, but I had already received my supplies from Beemerboneyard including a stock air filter so I used that.

My observation is that this bike ridden on paved (highway) roads for only 12K miles sure seems to have picked up a LOT of junk in the air filter and I wonder if maybe I should change out at 6K.

I have not noted any problems with power or fueling and my mileage averages 42 or better with gentle throttle use.

After the service I test rode it and all seems good, so maybe I'll pull the filter at 18K and see what it looks like.

Here's a smartphone pic of the dirty unit....

That filter is doing what it is supposed to, perfectly. I have them on my cars. K&N makes a cleaner that will make the gauze white again. I have used tire cleaner (Whestley's Bleach White) with the same cleaning ability. K&N's stuff smells like Fantastic cleaner. Never scrub..let it soak and rinse a couple of times. But after it's cleaned and dry you need to re-oil it. K&N oil has the red dye in it so you can see where the it's oiled. They don't take much oil as the wicks through the gauze. With the exception of the big bugs your filter still looks pink...it has plenty of use left before needing a cleaning. Get a soft paint brush and wisk out the loose stuff. It's good to go.

Thanks for that, I had no idea how to reuse the K&N. I installed the new stock air filter (aftermarket item, $13.95) this time around as I didn't have cleaner and oil.

Good move. Now leave it that way.

Stalling

When I put a K&N filter in mine it helped with some of the stalling issues. They typically flow better than a stock filter. I am kind of suprised you haven't seen or used one before. They are kind of expensive but have a lifetime warranty.

Thanks. I'll pass on the clean and oil routine.

Don't ever use a K & N filter, no matter how much you think they flow. They are covered with the special sauce (oil) that K & N thinks needs to be there to catch grit and debris....however while catching all the junk, it also covers everything down stream with fragments of the oil and eventually fouls out mass air flow sensors on cars and the Lord only knows what on motorcycles.

Use a good paper filter without any oils on it and just blow it out every 5K miles or so with an air compressor. I usually just take mine out when I change my oil and give a good hit with compressed air until it is clean again. Presto.....kinda new filter again!

To each their own. I have used K&N filters on motorcycles for a cumulative 500,000 miles and not experienced any of the issues you mention. 1 of the bikes had in excess of 150,000 miles and 2 had in excess of 100,000 miles. When you ride 5000 miles a month the benefit of cleaning and reoiling a lifetime filter that offers better performance saves time and money. I had all sorts of issues in the 88,000 miles I put on the K1200GT but none that you mention or due to the K&N. It is also not recommended to blow out a paper filter with compressed air.

I am glad to hear that you have had good luck with the K & N products. I have not been so lucky I guess. The oil from these filters has fouled out at least one of my Mass Air Flow Sensors on my Grand National over the years. Also, I can tell you that I have cleaned some of the oily residue off throttle bodies on motorcycles in the past as well, as the filter allows it to be ingested into the combustion chambers. It may not have any effects on the performance of a motorcycle, but I don't care for it. I don't see the necessity, so I don't use them any longer. Personal preference more than anything I suppose. If it works for you, then don't try to fix what aint broken, right?

Also, why is it "recommended" not to blow out paper filters with compressed air? First I've heard that from anyone, but I learn new things every day it seems.

Yes it is very common to over oil K&N air filters if you read the instructions you are supposed to oil them very conservatively. If done correctly no residue will pass. I would not recommend their use if over-oiled.

Paper filters are designed for one time use and can be damaged by application of high pressure air.
