What kind of Carb do I have?

[CoDean45]

I just bought an 89 Honda 250r and the guy I got it from really didn't know much about it. It has a 310 kit and a lot of other aftermarket stuff. It has a Keihin PJ carb on it and I really just wanna know what kind and what size it is. The numbers on the side of the carb read PJ15JAIL. Can anyone tell me what kind of carb this is and what size it is? Thanks.

if you take the carb loose and measure the inside bore (on the motor side/ or small side. example 34mm thru 39mm) the stock pj carb is 34mm, but you can buy 36 and 38 pj carbs. i don't reconize the number on the carb. but that is the factor brand that came stock on all trx250r's. untill u measure the bore i can't tell u any more.

yeah that's what I need to do. I just don't have time to do it right now. I can usually tell by the numbers but I just didn't recognize the numbers on this carb. Thanks for your help though.
