The one on the right is a early to mid 90's 160, one of them ones with a single circle is a 125 jet, I have seen whats technically marked as a 125 jet in late model powertorques from new. My manuals only have reference to the 160 and 125 jets, the 2 or 3 lines could have been from a twin or lightweight, unfortunately mine have been bastardised at one point or another and probably couldnt be a reliable source for the correct info.
