I have a 2002 zl 500. I have been fouling out plugs left and right (I replaced 16 plugs in 185 miles). I also consumed more a gallon and a half in that time. I took the carbs off to see if the pump was adjusted correctly and it was perfectly adjusted. I’m assuming that the pump is bad, but I wanted to see if there was any other cause that I am overlooking. I use klotz oil instead of factory oil so viscosity may be different, but I wouldn’t assume that would be enough to cause this much of a problem. Thanks!
