Engine Reving up

[tx650]

I have noticed one thing when running out of fuel and that is the engine will rev higher just before it stalls.
This could be a clue for some ppl trying to find a particular problem.

Also that it will idle, but no advanced throttle just before that.

well it leans out when you run out of fuel so that's why it revs up
