What kind of engine does a Harley 45 Flathead have?
In Class C rulings, flatheads are allowed to displace 750cc, while OHV motors were limited to 500cc. Harley 45 flatheads never needed lead. The reason tetraethyl lead was added to gasoline in the first place was to increase octane for vehicles with high compression. This is not an issue with old Harley flatheads.
What’s the difference between a Harley 45 and a wl?
The easiest way to tell them apart is that big-twin flatheads (UL and VL) have their drive chains on the left, and the 45 has them on the right. The WL series were manufactured from 1937 until 1952 and had a 45ci “high-compression” motor.
What’s the compression ratio on a Harley 45?
Most Harley 45 cylinder heads are cast-iron. Finding good used cast iron heads is cheap and easy. There is usually a number stamped into each cylinder head to indicate compression ratio. Heads marked 5.0 are low compression (5.0:1). If it reads 6.0 it is considered high compression (5.6:1).

Is the intake valve the same on a Harley 45?
You will see the same consistent gray line on the valve and the seat. The intake valves, exhaust valves, and valve guides for Harley 45 cylinders are same from 1930 through 1973, as are the retainers, keepers, and bases. Valve size is 1.625″ on both intake and exhaust, but they are not interchangeable.
