Kevin,

I may be wrong (someone will correct me if I am), but I seem to remember
the Continental rep suggesting Hoppes #9 is a not a good idea for use on
the injectors. Hoppes #9 is a copper solvent, and IIRC the Continental rep
said the injectors are made partially from brass, which is a copper-zinc
alloy.
