DELL`ORTO PHBG 21 sr50r compatible

Hi All :-) I have jus purchased a DELL`ORTO PHBG 21 carb and I have conflicting information on it's compatiability with my 2011 SR50 R ? My obvious question is...Is it compatible or do I have to send the carb back once I receive it ? and get something that is compatible ? :-( Thanks in advance for any help.



is the one you need
