Cylinders for Flathead 750cc / 45 cui.

Reproduction cylinders as used on 750 cc / 45 cui. Flatheads 1940 and up. Exactly made like their original counterparts, however, unlike 60+ years old WWII leftovers they have neither broken cooling fins nor stripped threads and they aren’t bored out to the 28th oversize. All that is required for installation is honing for standard pistons and a valve job. Valve guides and manifold nipples are pre-installed.

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.
