Reproduction crankcases which meet or exceed highest restoration demands. Cast from state-of-the-art materials and machined on CNC equipment for strength and precise fitment. Intended to work with stock or identically constructed engine components. Finished and detailed like the original counterparts so these cases will smoothly blend into your old mill to give it a new life. For ease of installation both case halves are carefully matched and feature pre-installed case bushings, which are line bored and lapped for standard rollers. Cam bushings are already in place and reamed. (for exact measures pls see below).
The selection includes cases with a smooth, uniform glass bead blasted finish and cases with an NOS (new old stock) finish. The latter means the finished cases are not bead-blasted but treated in a traditional process which gives them the appearance of new factory cases that had been sitting on the shelf for 50 years. Perfect for those "patina restorations".All cases feature laser-engraved CB production numbers, which are registered and filed.

James Gasket Kits for Engines: Panhead 1948-1965
Truett & Osborn Flywheels
They are made just like the stock counterparts, i.e. the left wheel is thicker than the right one (exc. JD), with the same weight and resulting torque.
An exception are the flywheels for Evolution Big Twins. They come as Torque Monster flywheels, i.e. unlike stock they feature a thicker left wheel for more lower end torque.
All versions are unbalanced and require adaption to the respective lower end components. All T&O flywheels feature pre-installed and replaceable connecting rod thrust washers, providing increased service-life and restorability.
