Uprating Honda BF75 to BF90

[Balthazar]

Hi gents,

Do anyone has experience ot knowledge about the uprating of a Honda BF75 carburetor to a 90hp?

I just bought this one, not checked the year yet but wonder if this is possible? Like restrictor removing in the carb or something similar?

Thanks for help

usually the diffence between the carb version, is the diameter of the nozzles and carburetor accelerator pump. find a workshop manual and check the parts and purchase the related parts of bf 90. without year made and engine serial number no more comment
