“The Bride” has an engine

Hooniverse & False Neutral regulars will know that I’ve been building a custom Bultaco street bike, “Bultakenstein,” for a decade. Many will also remember that I put that on hold a while back to work on The Bride of Bultakenstein: an unlikely Shepherd’s Pie of a motorbike that combines the frame from a Taiwanese-built 1974 SST Panther Black Shadow 175, a 6½ horsepower industrial engine, a CVT mini-bike transmission, and a random assortment of cast-off spare parts that had been cluttering my workshop forever. (For example, I’ve had the swing arm and front wheel for over 15 years.)

Why? Well, we did a podcast episode on a couple of Predator/GX clone-powered bikes that Garrett and Mike Festiva built. It gave me the bug to build one, too. Also, a 6.5 HP industrial engine is a ridiculously cheap way to re-power a derelict bike: my engine and CVT together cost me $180, brand new.

Well, my CVT bike is coming together much more quickly than my other projects, even though it (like all projects) had its share of unforeseen complications. I had selected this particular frame with hopes that it would not need extensive modifications. That turned out to be impossible, and I had to cut the frame and weld in custom-bent down tubes.

Most recently, I have finished the engine mounts. The chain lines up nicely, though I did had to modify the sprocket carrier in the Kawasaki Ninja 500 rear wheel, and add an idler sprocket on the swingarm pivot.

Next on the punch list: carb intake, shock mounting, steering stops. I have all the parts to rebuild the front brake, so maybe that, too.

    Is that a front drum/rear disc brake setup?

      The front wheel is an Inboard Disc from a Honda 250 Interceptor.

        I was wondering of it was one of those VFR250 wheels with the weird inboard disc. The rear angled cylinder may be unique, I can;t recall any actual motorcycle with that layout

          As for the rearward-canted cylinder, Yamaha’s YZ-F motocrossers and BMW G310 models have a slightly rearward slant. The Ossa TR280 is the most extreme:

        Oh, I remember those, all the disadvantages of a drum brake combined with all the disadvantages of a disc brake, and few, if any, of the advantages of either.

          …Which is why it ended up behind my workbench for 17 years.

    The Bride is no longer a roller.
