I've looked all over this forum, studying the back fire issues others have had. My 2002 Savage had been taken to a dealer by the previous owner to get the issue resolved, and I had no backfiring when I bought the bike.
In my thirst for power I halved the white spacer, causing much backfiring. I swapped the main up to a 150, also still backfiring. My question is this:
When I turn the Idle Air Screw out I get very few large "CRACKS!"
When I turn the screw in, Iget lots of little "pop,pop,pop, pop,pops"
I am thinking my Pilot is too small to meet fuel demands when the throttle plate closes. Could I be right?
Background:
Filthy air filter
1/2 white spacer
#150 Main
47.5 Pilot
Idle set at "who knows"
Small tear in outer edge of rubber on the "Diaphram Assy" #32 @
