Hi,

 

Can anyone tell me how I can tell how old my GM shortstroke engine is?

it has the letters F.G.M on the rocker cover.

 

Any idea's of age or where on the engine it is stamped.

 

Thank you

F.G.M. is Flemming Graverson. If there is any other numbers on the crankcases, usually just below the barrel then you could try emailing him.

hi mate ,no exactly sure of years but i think around 2004 gm changed the timing case slightly where the ignition wires come out , the later ones came with a rubber grey flat sleave and the older ones didnt ,they were just a hole ,and around 2008 the crank cases changed abit at the back just under the barrel where the breather hole is ,
