Spent a bit if time the last couple of evenings making a velocity stack for the 45 which will screw onto the amal carb I'm thinking if running...I'll let the pics do the talking...
nice work mate.
That is cool as fuck I wanna try!!
That is one hell of a chunk of alloy. You can get heavy wall tube and rather than turning the metal you can spin it and stretch the trumpet mouth out. Either way what you made is cool.
