Title: XR75 KO Carby Question
Post by: Hardex on October 14, 2008, 08:10:58 pm

Hi Guys.
Can anyone tell me if the XR75 k0 had a "20" Stamped on the carby top or did they have a blank carby top I know the carbies are an 18 mill so i figure they would have a blank top but i have been told the carby i have is original but i can't understand why it has a "20" on the top?????????
Thanks.

2 things this could be either a casting number or the top off a larger carby was used as i believe the slide size didnt change between the 18 and 20 mil kehin carbs

Sorry i should clarify the "20" is not stamped but raised up on the carby cap ,I have another xr75 k2 carby that has nothing on the top cap at all and the same with a 81 xr80 i have so im a little lost with this one.
