I think you mentioned this once before and I thought it pretty 
strange. The only thing that brings your RPMs down when you let off 
the throttle is the LACK of power output from the engine. So the 
engine just slows down, losing its angular momentum to friction. If 
yours really does slow down faster than normal, then either you have 
more friction, or less angular momentum (or both). Well, a lightened 
flywheel would do the latter, and I suspect that enough extra 
friction to make this difference would have destroyed your engine by 
now. The real question is whether your engine REALLY DOES slow down 
faster than normal? How would you know? What are you comparing it to?

The flickering lights really don't mean that it slows down more 
quickly, just that it undershoots. A certain amount of this is 
normal, and your engine may be perfectly normal.

Well, you've managed to post 2 of the most bizarre 
questions/observations that I have yet seen here. I really don't have 
any clue why there should be a light in your ash tray. If you pull 
the tray all the way out can you actually see the light? Perhaps some 
PO installed this light. I guess there are still some people out 
there who are that enthralled with their smoking.
