350X jetting question

[El'Capitan]

hey, my 86 X has a K&N and some aftermarket exhaust on it (no idea the brand) but i do know its not restricting any flow of the exhaust. how would i know if it had been rejetted or if it needed rejetting? thanks :beer

what does the plug look like?
white - is too lean
black --is rich
its better to be too rich than too lean
plus it will be faster

This is what people who buy jet kits without moddifying their flow system believe

its better to be a tan because then it will be faster and you will have the proper jet in it. Richer doesnt mean faster, just means it cant burn all the fuel your dumping in and will actually hinder performance.
