I have a cat delete pipe and an RB muffler on my '84 GSL. Should i get a jet kit for it since i did the exhaust work to it? I know with quads you should jet when you get exhaust work done so im maybe thinking its the same way.

 

generally no, but you might want to think about a bigger fuel pump and a good regulator. if you feed the carb about 2-2.5psi of fuel pressure its tuning is just about right for a stock block/open exhaust
