Start from the bottom! the crank is a work of art a perfectly crafted,
press up ,needle roller job with slim steel flywheels.
This push a Arias forged ,big bore ,squish piston via the Carillo rod.
The crank:rod ratio is dow from 2.6:1 to 2:1 by means of a shorter stroke.
Practically square at 76.5x76,=349cc long long way from stock Goldie 71x88mm.
Only problem you can not over bore it.If it get damage He will have to change liner every time
"So what" He said, My wife looks after the purse.
Cams are stock Gold Star!"BSA's original profile is difficult to improve.
"The inlet valve are central,the inlet track on the Gold Star is one side to the head and to mount a enormous carb in that position result in the instrument fouling the rider's leg. To overcome this George at Mez Porting cut away the manifold stub,welded up the hole and rewelded a down-draught stub central over the valve.
