Low RPM Backfire Through Carb - SOLVED!!
I have a 650 SRA with about 20 hours on it. It backfires through the intake at low RPM's, no matter how long I let it warm up. Did it since the day I bought it. It is now snorkeled, has K&N filter and a Dynatek box. Those mods seemed to help a little, but it still does it. Plugs are new, gas is clean, never been in deep water or mud. The air filter smells of fuel, and the plugs fowl very quickly.
I am thinking it is running rich. Any other ideas?? If it is, how hard are those pilot screws to get to? Do I need to remove a bunch of plastic?
