The damage normally only happens to one like SKOOLS said. I have a YAMAHA 250 that COMPLETELY lost one cylinder, yet it still ran on the other 5 and they didn't look that bad. It just proves that these engines run on a FINE line of just enough oil to live on with the VRO. If it leans out just a little, you can't predict what will happen. That fractional drop in oil though could have been just enough to finish that cylinder off, while the others escaped. If you think otherwise, look at how many MERCURY's have died on just one cylinder from the crank gear just beginning to slip.
