Do I have to re-jet?

[Troy86250r]

I just got an esr silencer for christmas. Do I have to re-jet again when I put it on? I also got an ac bumper with mud screen and an ac skid plate.:D

I wouldn't think so with just a silencer addition,,if she runs OK,,I'd leave it alone,,but I'm also not a 2 stroke guru.

i dunno about that rico becuase silencers do have a role on a 2-stroke if u buy a shorty or longer or fatter it changes the power band and 2 stroke are really weird jetting them u have to jet alot more often wit a 2-stroke i was rejettin my 80 every month...

If I have a 155 main in there now what size should I go to with the silencer on there?
