My thinking is jungos is like what I have been thinking, reverse of what I have been doing.


Jungos is

More like my rev.1


Open or larger ID at the vw plenum and smaller ID toward the head.


Look at the GL1500 carbs are more centered in the engine and with long runners the runners appear to be more opened at the carb end and smaller at the head


Engine w/ fuel metering more centered

GL1500 head intake ports are only .960" ID

GL1800 head intake ports are only 1.100"ID


Fuel metering very close to head port

GL1000 head intake ports are 1.412" ID

GL1100 head intake ports are 1.430" ID

GL1200 head intake ports are 1.258" ID *** this is close, would these heads add to a higher engine torque?
