Notice the 2 base gaskets???
As I am no expert with these engines I will take questions and or make mesurements for any one who needs them.
What I do know is strictly from the experience of running the same engine for 100 miles in a cruiser frame.
It's seems to have plenty of torque / is very well balanced / pulls hard up to about 8000 rpm with little effort.
I have been clocked to 34.5 mph ( garmin gps )
44 tooth stock sprocket. 26" wheels.
