These 2 carbs are for 86 to early 87 140's. So chances are the other 2 if they are larger must be a partial set of the 86 200XP carbs. In 86 and a few of the 87 200 XP high performance loopers they used a MASSIVE set of carbs. I take it they are almost a straight shot through the air passage through the center of em, if so that is them.
