Internals of the GO 3 Port Race Spec

Same clean machine work as the 5,7 .25 and .28
Closer tolerences= better fit on carbs
New crank for the 3 port Spec, this is where the top end comes from and the liner feel.
Carb boot has rubber o-ring installed to give a tighter boot seal.
New oring in the carb intake, alot of you who have the newest 5 and 7 ports and .25 and 28 will notice this as well.
Breakin was a breeze.
