[bulk] [dsn_klr650] air filters

[Dennis Angus]

I noticed a thread starting about air filters. After reading about the K+N filters some time ago, I bought one and installed it. This year I changed the carb to a Mikuni. When I pulled the carb, I also removed the rubber boot from the air box and found a very fine coating of dust inside. I can't be sure if the dust got by the original filter or the K+N. I decided to try a different filtration method so I cut out the raised section of the filter door, placed a fine screen in the cut out and attached a piece of after market filter material. I also placed a piece of screen in the original air inlet with the filter material attached. I oil the filter material the same way as the original. Now I can see the condition of the filters and clean them when needed and I doubt the K+N will ever need to be cleaned again. This modification has made a very effective pre-filter and it hasn't restricted the airflow. DAngus A-11

I have been flipping through my Dennis Kirk's dirt bike catalog and drooling over all color pictures of all the cool accessories. One of the first thing I would like to get is an beter air filter. What are the pros and cons of K&N vs Unifilter? What about using those filterskins over the filter? Craig A15 P.R.U.A.V.

Don't know about inexpensive, but I've been running Moose foam filters for a couple of years, and they've done great. Incidentally, if you don't want to squish your spare foam filter when you pack (although that's one of the advantages of foam), one of the Glad "disposable tupperware" sizes is a perfect fit for a KLR filter. A friend of mine loaned me a Twin Air filter for a flow test, and that one was too small to properly fit the basket. Don't know if that was actually a mis-labeled filter, or a one-time problem, but I couldn't get the base to seal up very well. Krokko -- Dr. J.

Fred, Thanks for your comments on both oil and air filters. I took a hard look at the stainless oil filter. One of the local guys bought one and really likes it. It sounds like it could be the way to go for lots of riding and not having to do more than change the oil and remember it has a filter. I keep hearing of folks who like the K&N filter. Maybe I'll change my mind about them after hearing enough good posts about their performance. Thanks again, Jeff

Krokko, Thanks for your comments. So far it looks like the Moose is in the running for cost and performance. Here's what I got with one phone call to a dealer. Twin $25.95 Stock $23.99 Moose $21.95 Uni $20.95 I'll keep the disposable tupperware container idea in mind.

--------------- I use a K&N air filter w/ a custom foam filtering modification on the once solid retainer plate. The ultra-fine dust present in my air-box after my weekend in Death Valley did not pass into the carb, let alone the area between the filter chamber and the post-filtered area at the front of the air-box that is drawn upon by the carb. Excellent performing filtration package, w/ higher than stock K&N airflow capabilities. Mike Torst Las Vegas

Mike, Thanks for sharing your experience. I'm glad the K&N is working well for you. I usually wipe the inside of an air cleaner with an oily rag so I can tell if dust is getting by the filter and to help catch some of the dust before it gets to the filter. So far the stock filter is working well for me but I haven't been in the dusty conditions like you've been riding in.

The forward air-box chamber gets misted by crankcase vapors as well. Mike Torst Las Vegas

This is a good idea, because in my experience, I found that the unmodified, properly-oiled K&N actually flows LESS air than the stock filter. My '89 would run lean with the stock filter and was harder to start cold than with the K&N. I do like the durable construction of the K&N and that's my main reason for keeping it.

-------------------- My feeling exactly - not enough surface area. I basically 'Swiss-cheesed" the retention plate w/ a few 1" I.D. and several .25" holes and used a 3/8" spacing grommet (so the foam would not be crushed when mounted snuggly), a 5/8" thick filtering foam (oiled), a HD mess retainer roughly a bit bigger than the in height and width than the K & N filter retainer, safety wire on the winged screw, and retain the far end of the wire w/ the air-box door screw. I noticed by dust patterns on the foam that air was being drawn though the filter media in addition to the surface of the K & N. All in all, it worked flawlessly in talcum powder dustings - the air-box was a silt fest, but nothing got past it into the forward air-box chamber. Mike Torst Las Vegas
