My '84 200x is feeling pretty strong after the overhaul for the most part. The lowend is very torquey but when I wind it out it feels like it starts to lose its thunder like its not getting quite enough fuel. Its got a K&N filter, I did a mild port job on the head, more or less cleaning up casting flash and opening up the throat of the ports where the valve seats meet the head casting, and a .040 stock compression piston and stock exhaust so far. The spark plug is spotless so far but I don't have that much run time on it yet either.

would definitely go up a couple jets. buy 3 or 4, they're not expensive. K & N alone requires it.

Does anyone know what the stock main jet is on an '84 200X?
