HMF rejetting?

[mjcat500]

Hello.
Does anybody know if you need to rejet a carb on a 06 500 4x4 with a HMF muffler on it and if so what size jet?

im sure you will i couldnt tell you what jet to use cause it depends on the temp. what i would do is try to find someone with a same setup and go off of their jetting and buy about 2 bigger and 2 smaller jets. Or you can just buy a jet kit for around $40
