I have this square shaped bing on my maxi from a '96 Korado (yup it's backwards, but works fine) marked 18/14/108. It is lovely but needs a bit bigger main jet and so I may try a few sizes. These are fatter than the jets off of the earlier bings, and the ones from my old carbs won't work. Is there someone who has these for sale? Is there another jet that will screw in, like one from a Yamaha or something if not? Has anyone tried interchanging jets from another brand?
