[Clue to poor gas mileage problem?]

http://jbmindustries.com/Yamaha650.html

these are the best and cheapest I have found.

 

I'm wondering what effect this condition has on my poor gas mileage problem, and what it means.

 

 

I took the diaphram covers off the carbs.

 

 

All of the diaphrams had 2 to 5 pin holes in them, plus

 

Carb 1 (left front), 2 (Left rear) and 3 (Right front) as your sitting on the bike,

all had a film of dry dirty, greasy coating the inside surface of the covers, and the carb surface behind the diaphrams.

 

The diaphram had a sticky feel to it like wet paint. ( probably partially disengrating rubber coating from previouse pin hole fixes with liquid rubber)
