Lost oil drain plug at 65mph.

I changed my oil last week and torqued my oil drain plug to spec but she fell out yesterday when I was going 65 on the highway. I didn't notice any off sounds other than the motor cutting. After I pulled off to the side of the road my bike dropped about a quart and a half of oil. What kind of damage could I have caused? I replaced the drain plug and crush washer today and filled it with oil, I tried the starter to make sure I didn't seize the motor and it turned over fine and started but was rapping pretty loud so I shut her down. Any ideas?
Thanx
Bryce

Ouch! Sorry to hear.

Rapping after running out of oil sounds like bearings in the bottom end. If it ran long enough to damage the bottom end, the cam bearing surfaces in the head probably have some damage as well.

Thanx wylee. I had a friend look at it and he said the same thing. I'm hoping I can save the engine.

WOW, I had never heard of doing that. So you replaced all the oil with MMO? And then after 500 miles went to straight Syn?.. Just out of curiosity, did you pull the oil filter and check for particles? Keep us posted after you get some more miles on it and how it is doing please, I might need to add this procedure to my ever growing manual. Good luck with it, I sure hope that works for the long haul.

WOW is right. I would have lost money on this bet.

Good news. Keep us posted.

I guess the theory is the bearings nearly seized from heat and the "rapping" was more like the sound of a KLR idling to slow. In that case, the marvel mystery oil would help the now tight bearings break in and wear close enough to spec. :shrug:

I would think the engine life has been reduced, but the question is how much.

I'm with you... If they were too tight from the heat build up, and then magically "fit", they have to have shifted in their race/seat.

I would pull an oil sample and see what material is showing - betting you see high levels of copper and tin.

Good luck!

Don't know who this clown is with the same user name as me, but my bike is sitting in the basement waiting to be torn apart to diagnos the motor noise. I will keep you posted.
