Cylinders as used on 750 cc / 45 cui. Flatheads 1940 and up. All that is required for installation is honing for pistons and a valve job. Valve guides and manifold nipples are pre-installed.
Both cylinders require pistons and piston rings of the first oversize (+0.010"). The pressed-in valve guides are honed to 0.10-0.12mm clearance.
Cylinders which are not offered as complete kits, i.e. with pistons and rings, are not finish honed. This job must be performed in a qualified workshop.
