Ms460 mods and jetting

[cd1979]

Hello I have a 460 that I want to put a max air kit and dual port muffler on, will I need to rejet the carb or should I be able to get enough adjustment out of the carb stock? Also is there enough of a difference between a dual port muffler and a bark box performance wise to justify the cost difference?

No re-jetting needed, just a bit of a tune is all. As for the muffler covers, I don't have much experience one way or the other.

Ok thank you

Get a dual port preferably with spark arrestors, more torque and its not nearly as deafening. You will need to adjust the carb a hair, a clean and rebuild paired with a new fuel filter never hurts.

Thanks for the advice
