I'm trying to figure out what Carb this is. It does not appear to be stock. I've done some searching with no luck yet. The bike is fouling plugs and I wanted to return it to the stock jetting, but I'm not sure I can with a non-stock carb. Also, anyone know what the red and blue plugs are on the left side? The red one opens up into the intake, and the blue one has a 90 jet in it. Any help would be great. Thanks!
