I had the exact same problem on a 06 yz450. I used loctite and jb weld to seal my up permantely. It does not leak and I use the bottom drain bolt to change the oil. I am also concerned that I am not getting a sufficient oil change. Dirt Rider magazine had a good arcticle explaining the Heli-coil and Timesert, but I dont know how to drill out the case without getting metal shavings inside the engine.

Hopefully someone can explain this to both of us. Maybe GreyRacer has an answer.

Good Luck.

Same problem (left side drain plug) popped up a while back and I have been getting by until yesterday when some threads showed up on the bolt this time. I like the idea of the timesert so I might just make my own since I have a lathe and the materials on hand. If a helioil or part of one got into the crankcase it would do some major damage.
