Short work rant, have an Alfa.
Just had a guy call in, "I just bought an exhaust for my Harley and if I give you the exhaust part number could you tell me what fuel injectors I will need for my carburetor?"
Yes, I know exactly which fuel injectors you need for your carbed bike based on some random exhaust part number. The correct answer, of course, being NONE, because you can only have one or the other, not both. I will keep a weary eye out for your CL special price on that Harley though...
