Here is an engine speed versus bike speed chart I made. At 4,000 RPM 55 MPH in fifth gear and 62 MPH in sixth gear. This engine make good torque right across the board and right where I need and want it.
The engine will pull fourth gear at 25-30 MPH with the close-ratio tranny and the overall gearing is pretty short.
The engine sounds marvelous! Though it is a 60-degree instead pf 45-degree the rods still share the same crank journal so up until about 3,000-3,500 RPM it sounds like a small HD. After that and up to 9,000 RPM it sounds like few other bikes.
The Street Rod has higher compression, better heads, better cams, and 2x42mm throttle bodies instead of just one 38mm.
