no oil

KEEP YOUR KEY ON YOU.

You don't ride another's bike without permission.

I would think the bottom end is still OK. Probably enough oil clinging to the surfaces of the bearings for three miles. I would think the clutch and trans are probably OK too. The pistons and valve train may be another matter. You just need to check for symptoms of top-end engine wear - low compression and/or excessive oil consumption.

As others have said, you may be ok. My car mechanic drained the oil out of a retired shop car, an 85 civic with 330K on the clock. He then ran it all day just to see what would happen. It ran fine with no problems at all and he still uses it, now with 360K miles! So you never know.

we need more details here...

#1 Why is said friend still a friend?
#2 How much oil was really in the bike?
#3 Why did he do this?

But i bet your bike will be fine. Just fill it up with oil, and start it up. Don't rev any, just let the oil circulate.

I wouldn't be surprised if it's still ok.

Think about it.

roller bearings everywhere (no journal bearings which would cook).

as long as there was some residual oil to wet the cylinders and keep the cams damp, it should be ok.

Although, the farthest I've ever rode without oil is to the end of the driveway.

Assuming your bike is an 8 valver with the roller bearing crank, there might not be as much damage as first thought. You might want to pull the valve cover and look at the cams, and do a compression check to get some idea of what's going on there.

Good luck.

Yikes. 3 miles with no oil is a very , very bad thing for a motor. Are you sure it had NO oil at all? Not a drop? Suprised it made it that far.

Most motors won't take that kind of abuse, but if any can, the GS motor may be able to. Good luck.

One of my friends decided it would be cool to drive my GS550L 3 miles without any oil in the engine. Should I expect any damages, besides the ones that are going to be done to his face?

Suggestion #1) Kick your friend right in the nutz.
Comment #2) Your engine is most likely a boat anchor now. I would be amazed if there was no serious damage.

Comment #3) WHY???????????

Um, stupid question, but why wasn't there any oil in your engine?

Only thing I can think of, put oil in, go ahead and change the filter (to catch any metal particles, buy a good one!), then do a compression check. If you hear clattering or knocking, your friend owes you a new bike.
