I am helping another with a project and he has a Invicta with a JAP engine. The numbers are LYB.
I understood that the LY would designate it as the 550cc model engine, and that the B would be the year. I cannot find any reference to B having been used by JAP to designate a year, would you have any suggestions as to what engine this might be.
Engine Data page gives the same information. Ed.
I am working on getting some pictures. The bike I have not personally
seen as it is on the East coast of the states and I am on the West coast.
However the person will forward some pictures when he gets a chance to
take them. All I know is that it says Invicta on the gas tank and
has a carbide light, pedal starter, chain drive, Armac carburator, I believe
a three speed
tranmission, single cyclinder side valve, approximately 30cc or so from what the guy says. Sorry this is all that I know currently
