Oil Drain Plug washer

I have gotten into, what I think is a good, habit of changing my trans oil after each weekend's rides. The only annoying thing about this is that with my 2003 kx125 I have to replace that oil plug washer (gasket) each time.

My Kawasaki shop charges (amazingly) almost $3 bucks a washer! Online I have found them a little cheaper

92065 GASKET,10.5X16X1 92065-058 $2.39

As of today the shop is out of stock ... as is motosports.com.

Has anyone found a reasonable alternative to this pricey little washer/gasket?


I use a moose magnetic drain plug and never change the washer on it.

After market drain plugs! I had no idea!! Thanks!!!

The drain plug washer is a crush washer. Some folks, who are probably technically correct, will point out that once it is crushed, it should be replaced. However, I reuse mine multiple times and only actually change them in my "big" tuneups, which include things like lubing cables and changing the spark plug.

You can buy a pack of similarly sized aluminum washers at AutoZone (they are over near the oil filter wrenches and stuff like that) for about 1/4 of the price per unit of the OEM washer. I use those, and I have had no problems.

One thing to keep in mind is that like the crush washer on a spark plug, once it has been crushed, the torque spec from the manual is out the window. On a non-new crush washer, just tighten the drain plug until you feel like it won't vibrate out; don't torque it down to 20 ft. lbs. or whatever the manual says - you are more likely to strip the threads in the case with a used crush washer than with a new one.

Another thing to remember is that lots of people, me included, do stuff that is not 100% "right" with no bad results. That does not mean it is smart, it just means we have not found out why the factory says to do it a certain way yet.

See you on the trail.


Thanks for all of that! I appreciate it! :thumbsup:

Some other threads on other forums seemed to be of the opinion that the washer is more over torque protection than seal. If that is the case then, as bmcd308 suggests, just snugging up the bolt enough to prevent vibrating out would be key.

      Hi all,
      I have a 2004 kx 250 2 stroke and it wont start.  it only backfires.  I was out riding it one day and came up to a stop so the bike was just idling and it started to try and die so i revved it up a few times then let it die and now it wont start back up.  It only pops or backfires when you kick it.  Its getting good spark and i just put a brand new plug and coil in it. I took the reeds apart and they look like they're brand new.  It was running great before so i dont know what happened.  Im thinking it could be a fuel problem even tho the plug is a little wet if you take it out after a bunch of kicking.  Any help would be greatly appreciated

      Alright, found three bikes all located where i live in Texas. I know they're all very different, but if you could tell me what you think each bike is worth, and which one would be the best deal. Thanks.
      Notes: Both 2 strokes have new top ends. I think the front brake lever is broken on the kawasaki.
      KX250 2002 $800-$1000?

      YZ125 2000 $1250

      KTM 400SX 2002 $1200

      So I'm at a bit of a cross roads, I currently own a 06 rm250 and I love it. I also have a 02 kx250 which I'm selling with intent to buy a newer two stroke. I can't afford a newer ktm and the older ones aren't that great and kawasaki never impressed me. so I'm stuck between 06 yz250 and 05 cr250. I've heard the yz and rm after 06 are almost the same bike just the Suzuki handles better and the Yamaha has better suspension. So I'm not sure if I wanna buy carbon copy of my bike with slight differences. That's why I'm interested in a cr250 I heard the 02+ models RC valves are shit garbage but was mostly fixed in the 05-07 models. I ride at a track and at some bogs down the road from me. So from people who have owned both, what would you recommend. I know the cr is known for a hard hitting power band which I enjoy since im an aggressive rider. Should i just see which deal comes my way first.
