Hi, This engine case does not have Breather pipe holes. Is it from early 50's model? Any idea.

Where does the breather hole come.

thanks,

Our hosts have a set of used early Bullet cases for sale, engine number G2/18399, quite close to the engine number on your crankcases. Looking at their pictures there seems to be some sort of breather on the timing side, in the corner behind the back of the tappet chamber and the timing chest extension for the magdyno drive gears. Later breathers were taken off the drive side crankcase half.

Hi, these early engines breathed through the crankshaft and out through the bottom of the chaincase. Vince

Thanks dude. Got it. 1949 to 51 model G2 had this type of Breather. Primary cover has breather pipe.
