I need to find a missing piece of doohickey. How do I get to the oil screen? Do I have to drain the cooling system? If so, what kind of coolant do I use to replace the old stuff? If I lean the bike over on its side, do I still need to drain the oil? Thanks in advance, John in T.O.

Pull the water pump cover and impeller off. Then pull the clutch cover off. remove the screen and pick out all the bits of junk. Put a finger and/or a magnet in the screen hole and look for more junk. I like to do this in conjunction with an oil change and even back flush the screen hole with oil in hopes that any other bits will drain out the bottom. I just did this yesterday on my A3 'cause I had a "feeling" the oil was not circulating as well as it could/should. The bike seemed noisier the last couple of days even though the crankcase was topped off. Sure enough, the screen was so full of metal, RTV and rubber guide bits such that the vacuum created by the oil pump collapsed the screen! I should have done this 5000 miles ago when I bought the bike, but I think I caught it just in time and the bike's life span may not have been shortened too much. When buying a used KLR from an unknown source, I recommend the first thing you do along with changing the oil is check the screen! Mark

Hi list, I`ve been thinking of doing this oil screen check but It seems like a lot of work to check the oil screen when there is no other reason to take the side cover off. And I haven`t heard of anybody having any problems from a clogged oil screen ( on this list 2,500 KLR`s strong ), not to say there is not any shit in it. I think that sooner or later the cover is going to have to come off for some other reason, ( water pump seal or clutch ) then check the screen. I would like to know how many people went thru all that trouble only to find very little in the screen???I would also like to know how many miles people have on there bikes that haven`t looked at the oil screen w/ no problems to the motor???? Is there a way of installing a oil psi gauge???? That might give an idea of how clogged the screen might be. GARY PARECE ,98 Concours 101k , 2001 VFR 4K mi.,2002 Suzuki DRZ 400 E, 2001 KLR 650 1K

There is a way to check oil psi according to the manuel. The hole for hooking up the guage is near the water pump. I bought my 94 in Nov of 03, with only 9500 miles on it. By time I got it home it had 10,000 miles on it, and I pulled that side cover off to check/clean the screen and repaint the cover. (Hey, don't laugh. It looked like brand new when I was all done with it) I found quite a bit of crap in that screen. Over half of the screen area was covered. Mostly with very thin shavings of black rubber. I think that was mostly from the rubber on my balancer gear. I found a small chunk of metal too, that I could have sworn looked like a piece of doohickey. But when I changed that out I found my stock one to be in one piece. Bent up a bit, but still in one piece. One thing that I do keep an eye on closely while I'm doing a valve adjustment is the exhaust cam cap. That is the cap closest to the front right side of the bike, and the last place for oil to get to. I figure if the pressure is dropping because of oil flow constriction, I should see the cap getting scored and worn in between valve adjustments. MrMoose A8 (Barbie and Ken special)

There have been reports on list of oil pump failures from clogged oil screens I believe. Millerized, didn't your bike shit the bed for that reason?

*Everybody* is going to find the screen full of gasket sealant as BigK likes to slather that crap everywhere in the engince. Plus you'll find a whole bunch of metal shavings and the like. If you want some idea of the crap in the oil, next time you do an oil change, cut open the oil filter and lay the pleated material flat. You'll see a lot of little bits of aluminum and gasket sealants. It's amazing that our engines last as long as they do shedded all the crap they do.

As everything KLR related, some people have no problems, some people do, it's the nature of the beast. I'd recommend checking it for the peace of mind. It's not hard and you'll feel better about your bike afterwards. Z DC A5X A12X

I checked mine last week and discovered that one of my clutch friction plates was in about 12 pieces (clutch still felt fine). Here is all the junk that was in the screen: http://jeffwight.gotdns.com/moto0.jpg

Hi, well I did it . and I found almost nothing in the screen at 1,900 miles . This bike only had one valve adjustment from dealer (previous owner ) and I did the doohickey mod. As long as I own the bike and i`m careful while servicing it (gasket material / goop and etc.) I don`t plan on checking it again until there is another reason to take the cover off ......Next will be an early valve adjustment because trip in may/june (Moab) will be around 6 K miles. With 1,900 miles and whatever I put on it till then and the trip, will get me way over suggested intervals , plus my motor is quit witch tells me that the dealer didn`t set them to loose end.

The problem with the screen isn't so much varnish, but an over-abundance of crankcase seal material that breaks off of the center seam and finds its way down there. But it _is_ hard to say wether or not this has ever caused oil starvation. I don't remember any specific cases offhand, anyway. Krokko -- Dr. J.
