speeding to start with you are in the raptor section and if you are asking if they have a choke then yes. it is technically an enrichener but to the average rider it means the same thing. ( a choke decreases the amount of air in the mix to make the mixture richer and easier to start, an enrichener adds fuel to do the same thing).
if you just posted in the wrong section and are asking about your warrior, they have an enrichener as well. it is a black button on the side of the carb.
in a nut shell you change your jet sizes to adjust for elevation and other factors that effect the fuel to air mixture. without a significant change to the machine or elevation jetting is not something you just "do". why do you think you need to change your jetting? have you replaced your plug, ran the machine for a while and then checked your plug? any recent mods? elevation change
