any way to tell what carb i have?

[86250rbanshee]

Is there anyway to tell what carb I have on my 86' 250r, I wasn't sure what brand came stock on it right now on it is a Keihn, no idea what size, is there anything on it I can look for to determine what it is?

Thanks

that was the brand for the stock carb, many have bigger carbs though 36mm for woods bikes and 38/39mm for mx bikes.

Stock would be a 34mm kehein PJ. on the side of the carb, right above the bowl there should be two letters with some numbers after it. If you look in the "Clymer" service manual, it will tell you what year carb it is, if it is a stock carb.

My clymer says pj05a is the stock carb # for an 86.
