I finally got the new engine for the Rokon:

It’s going to take some work, and more parts to get it in the bike- A longer torque converter nut and lock tab (ordered) and some odds and ends like new grade 8 bolts, washers, fuel hose, and the like.

Another view:

U.S. Motor Power has installed an angle plug head and a 1″ carburetor and elbow on this engine, and along with the square exhaust port-

It ought to run a bit better than the old, worn out mill.

Today I’ll install the cylinder head bracket and head bolts, and I hope to get the engine in the frame tonight.

More to come.
