If you’ve never heard of Allen Millyard, let me first say: here is your opportunity to get out from under that rock where you’re living. There’s a worthwhile rabbit hole here; go find out about this man’s life and work.

If you have, we very much hope you’ve also been following his most recent build. This man started with two Kawasaki S1 250cc triple engines, and is in the process of building a motorcycle around them. He’s not just combining the engines, though. He cut the crankcases apart to create a single four-cylinder bike out of a pair of triples.

Further, he doesn’t pop them on any fancy machines. He cut them apart with a hacksaw, including a pair of right angles, and joined them mid-cylinder. With a small hand-held welder, after heating the crankcase on his back yard barbecue grill.

Millyard’s videos are not exciting or full of creative invectives. If you were a fan of any TV shows out of Orange County, you may not enjoy them. If, however, you love watching hand-crank lathe work, and have ever enjoyed watching Bob Ross paint, you will love watching Millyard.

His videos often hop from the “back garden” into the kitchen, where we all witness cookies or cakes coming together. Sometimes he films the birds that come visit him while he does his work outside, on the lawn. Every Little Detail

This series of build videos details every single step necessary to build the motorcycle he’s aiming for. Cutting apart a case means rebuilding the crankshaft, transmission, and gear shaft. He then gives it a full top end rebuild, and bores out the cylinders so the bike will be a 550 when all is said and done. Then he has to figure out the carburetor setup, ignition timing,  and a frame for the bike. Current Episode

His latest video, episode 9, details the preparation of that frame. In order to receive the engine, that frame needs custom bolt holes and spacers. Compared to everything else he has done so far, at first this seems a bit on the simple side.

He installs steering head bearings one ball bearing at a time, and includes a grease nipple before installing the swingarm. The rear shocks then connect the main frame to the swingarm. He installs the rear fender with a bit of a struggle (honestly he makes everything look so easy), the battery box, and then pops the engine in. After a quick break for hedgehog cupcakes, he custom-machines the rear engine mount spacers.

If you don’t get the idea by now, watch the videos when you need some stress relief. Instead of happy little trees, Millyard sees that things “come together nicely,” and he’s “really pleased.” All Previous Episodes So Far
