Rejetting for exhaust with stock air box/filter

[anthony8488]

Maybe I'm not searching the right keyword, but I have an 82 cb750sc Nighthawk with #68/#102 factory jets. I know definitely with pods and exhaust jetting is required but would/should I rejet to go from my factory 4-4 to a 4-1 exhaust (looking at Carpy's Yoshi style to keep the center stand option).

I have found some post suggest #75/#110 and some say its for pods with exhaust and some post say its for adding the exhaust alone.

If I need/should rejet the carbs for the exhaust I was looking at this <a href="http://www.pjmotorsports.com/keihin-jets.html#main jets">site which I would need to buy Keihin Round 99101-393 Main Jets but would need #75s & #110s?

Few exhaust changes require rejetting. If in doubt, the spark plug will tell you. Change the exhaust and run it for a while, then check the plugs. Make sure you pull them before running and take pics of them for comparing.
