It's always a good idea to mock up these motors before you get too carried away with assembling parts for good. The cylinders didn't fit, requiring sanding, de-burring and plenty of aspirin and head scratching. It's nice if the cylinders can move on the base studs a bit when aligning the intake manifold.
I'm building a 1956 KHK for my buddy Dave. I get boxes of parts in the mail from him. Sometimes I open the box, and the parts are totally trashed, greasy, dented, rusted and broken. Other times I open the box, and the parts are the most beautifully polished, original parts you've ever seen. They are so pretty you hate to touch them, and you have to be ultra careful not to scratch anything. This was one of the "shiny times" I opened the box. Now cleaning, checking threads, pressing and sizing bushings.
I found this one . . . opened the box and had to make an offer on this original NOS Big Twin 4-Speed Kicker Gear. The price was right - and it went right-in-my-pocket. A guy can build an entire motorcycle after buying just one particular part that sets the stage - and taints your interest.
Now I'll have to look for a nice transmission case, mainshaft, some gears . . . and build a transmission. Or just put it in a box until the one in my bike wears out? Probably a smarter thing to do . . .
. . . to look like this. Every guy needs one. If it's a big city, or a small little town. For a quick flick through town, up the hill, down the alley . . . easy parking. Park it in the garage, in the shed next to the mower, or lean it against the fence (with a blue tarp over it). No battery. No Problems.
We rode to the drag strip one Saturday, and all these older Harleys rode in right after us. It was cool, since most times it's a sea of Twin Cams ! That's dad's ol' '65FLH (nearest) running a late model CV carb and Spike timer. The last few days he's been fabricating a 42mm Mikuni flat slide. He had it running in the garage, and said, "It's definitely more responsive." The CV has a flat spot about off-idle that we just can't seem to ditch . . . it runs ok, but ok sometimes ain't good enough, (you know what I mean)
