Choose the jets size from the sales drop down list. Only ever use genuine Mikuni parts when attempting to correctly tune out rich or lean engine conditions.
The Mikuni BS30/96 pilot jet has a total length of 14mm and thread outside diameter of 5mm. There are 6 side bleed holes. If confused what separates this from the VM22/210 jet, it is that on this jet the sized flow hole is set just 0.5mm back from the top end (non threaded end) of the jet in a concave scolloped hole rather than being set back 6mm in from the end as it is in the VM22/210.
