Aisan 28/32 Jets

Full Screen Mode


The Aisan 28/32mm & 30/34mm carbies are the 2V downdraft types. The idea behind this page is to provide compatible jets for the CB and H series carb engines. The venturi neck sizes are listed for comparison. The throat sizes are generally 28mm for the primary and 32mm for the secondary, although from the list it is obvious a few of them are 30mm & 34mm. This doesn't change the issue of interchanging jets between both models.
