Greetings to all on the list;
My bike has lost some gas mileage recently; up to 20 miles less per tank
riding the same way as always.  I cleaned the K&N filter but that did not
help.  The bike now if back fires when accelerating fast and "carb farts" very
easily now even after being warmed up.
Plugs:  Took them out and they look good: dusty gray, no oil or soot buildup.
1996 883 XL, bit over 50,000 miles on her, Stage I upgrades many years back.
I realize this is probably a carb issue and need to check connections etc.
and that will be a first step but was hoping anyone with experience might have
some suggestions or good approach to diagnose what is going on.  I have the
service manual and will start with it but my experience is a bit lacking
here.
Thanks ahead of time.
Anthony
