Check your drain plugs !!!!

3 posts in this topic

Changed my oil yesterday, found the drain plug was loose! I know I'd tightened it. The only thing keeping the plug from spinning all the way out was the safety wire.

Since this almost catastrophic event I've asked around and found that the aluminum washer that came with my '03 YZ450 could be the culprit. I've never changed it, never thought I had to. Dealer says the crush washer is only good for 4 or 5 times (or very few) and then it no longer has any elasticity left in it (it is fully crushed) and that allows the drain bolt to back off. Scary!

I always check my drain plugs at least acouple times a ride, like when ever I come in from a moto. I just look at them to make sure they are nice and tight and every thing.

Good advice as they do come out.

I can tell you the result is not pretty, I had to replace a piston and cylinder due to mine dropping out. :thumbsup:
