Iv'e been building bikes for about ~20 years, for myself and a few other. Figured I'd put up some of the latest ones.
This is what I started with.

Took the frame to Irish Rich to have him ruin a good swingarm frame by making it a cool hardtail with the old style axle plates.
And got this back (mocked up to get all the tabs welded in the right locations).

Love the lines of a hardtail harley frame. Rich did good as always.

The guy I got this heap from said it had that "old shovel knock". I knew when I could feel the knock on the outside of the cylinder that things were not good inside. SO I used that to get it at the "right" price.

The left case had been swapped for an evo case half and the deck was not milled. SO...the cylinders were cocked to the right and that made the rod bearing and wristpin circlips very unhappy. Result was a spit out wrist pin circlip and trashed crank pin.

I just happened to have a set of 74" flywheels and pick up another shovel case half...decked it and here are a few pics.

A new set of japanese rods, bearing and crank pin from Eastern. These are better the the original HD parts.

Got less than 0.0004 runout on the pinion shaft and .0006 on the sprocket shaft in under an hour. The tapers on these old wheels with 84,000 miles were still perfect.

and that's the bottom end.

For the top-end I am reusing a set of cylinders, heads and pistons that only had a few thousand miles. I'll be going to wiseco 9.5:1s later.

Thought sporty tanks worked better with the "skinny" bike style. And had the 3.5 gal tanks slated for another build.

More to come.
