Question catalytic converter can be permanently damaged...

"In addition, the catalytic converter can be permanently damaged if the motorcycle is allowed to run out of fuel or if the fuel level is allowed to get very low. Always make sure you have adequate fuel for your journey."

After reading this in the Owner's Handbook (pg 50), how is running out or low of gas going to damage the catalytic converter?

It shouldn't. That's crazy. Run out of gas and the engine will die. The end.

How do you not occasionally get very low with a 3 gallon tank?

The fuel pump could momentarily draw air causing the engine to experience a sporadic misfire condition resulting in possible damage to the catalytic converter.

Yes a misfire might damage the catalytic converter or get it even hotter than usual to the point of melting the internals, but who would ever know? I would be more worried about the fuel pump running dry and suffering damage through lack of lubrication. The alarmists that write the manual have a mindset that says every potential mishap should be blamed on the owner even if that means being imaginative and economical on technical accuracy.

The catalytic converter will also be seriously damaged if you remove it, replace it with an X-pipe, and then throw the cat as far as you can, over the back fence and into the neighbor's yard.

I was wondering what all these metal parts strewn all over my yard were. Thought they fell from the sky from passing jet liners.

Nah, if the pump sucks air, the engine has no fuel to burn and can't really cause any damage if the engine just bogs. I've never killed an engine through fuel starvation but I imagine you probably wouldn't run it that low anyway.
