Default Oil drain plug drips. What's the solution?

     

Just bought my 16 year old a 2000 cr 125 r. pretty clean bike, but dripping oil, I assume gear oil from the head of the drain plug. His old ttr 125 drips engine oil from the drain plug. Should these have a copper crush washer? I thought the yamaha wasn't suposed to use one...but what do I know? Any ideas on what will stop it?

Thanks

The CR should have a washer. If the washer doesn't stop the drip, wrap some teflon tape around the bolt.

Yes it needs a copper or alum crush washer! The leak will stop as long as the threads aren't stripped!

Ok, if you don't have that washer and it's too hard to get from the manufactor, then go to Autozone or another auto parts store and pick up a drain washer kit. It will have several styles and types and sizes that can be used for your bike and it will be cheaper than the original, which no one stocks.

Makes me happy for my local dealership, they stock things like that.

Like the drain washer kit idea though, might be a good thing to have on hand for the vintage and post vintage bikes.

I wouldn't use Teflon tape as it can shred easily and get in the case when you go to change your oil. Get a washer. If I were to use tape it would have to be the petrol resistant type as it is thicker, and even then would twist into rope and only wrap several times at the base of the head not the threads. My .O2

I bought a 99' CR250 several years ago that had a stripped drain plug and dripped... The threads worked fine till you went to tighten it, then it would just keep rotating.
I drilled out the bolt hole a size larger, and installed a tapered pipe plug so it wouldn't protrude from the case and get hit again (the guy told me he cased on a rock and screwed up the drain bolt that way)... anyways, it was easy to drill and tap the new hole, and it worked like a charm!
Just be sure you flush out the gearbox if you do any drilling to make sure no shavings remain in there..
