it dont matter what type. just order some keihen jets. or go down to your dealer. they're all the same.

ok i believe that if you buy a full jet kit from like rockymountainatv.com (45-50) bucks. it goes up to 170. but in my case i wanted a bigger jet so i looked for a 180. if i remember right the cr250 has the same carb. i got my 180 jet from championshippowersports.com

your jet number is going to be 99113-ghb xxxx
the xxxx is your jet size for example a 170 would be 1700 and a 180 would be 1800 hope this helps.

Why are you running a 180 main? What mods do you have done?
