Carb question

[patches85]

Anyone know what type of carb a stock 400ex has on it. I know it is a keihin but what type. I need to order a couple of jets

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

the jets dont matter

what size jets are you looking for?

Ok Im at 155 now I put a K&N on so I gotta go up. Local shop only has 155 and lower.

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.
