i was told that u are suppose to jet your carbs after getting an aftermarket exhaust does anyone know what size to put in do i go up sizes or down
is it a hard job to do im a mechanic and worked on car carbs lots so i dont think it would be a big differance any hepl would be appreicated

You will most likely have to increase the jet size so that you provide more fuel for the increase in HP and exhaust flow rate. If you're just doing a slip on system then a dyno jet kit stage 1 will have the jets you need. The biggest problem is that you will most likely have to setup a gravity feed remote fuel tank because you will have to remove the tank to get at the carbs and do the jetting making it so you can't run the bike without doing the remote tank. Hope it goes well.
