please please please.
find a real dealer.
you can only use the diagnostic test lamp on that engine.

hey, thanks
it is a real yamaha dealer, but im in the uk and this engine was never released over here, i shipped it in from the states
yamaha UK cant give the dealer any details about it. And none of us can find the diagnostic plug. does it even have one?

yes it was.
no there is no dedicated diagnostic port and no Ox66 motor ever had one.
just like ALL OX66 motors you unplug the egine oil tank and plug the diagnostic test lamp in its place.
