The Dynamo sure turned out super. Was that the original color of the frame? Glad to hear they prepped everything properly before coating. I wasn't going to powder coat the z1r frame but now I think I will. I want to preserve the metallic Identification tag on the steering head which wouldn't survive...

That's coming out really nice. I talked to those guys at SDP just as they opened up. I may take a frame to them to see how it turns out.

I've wanted to add this rotating attachment to this bike stand for a long time. I still need to make a crank to insert where the hand wrench is now. The engine adapter as you see it now is just for holding and rotating the motor during the painting process. I can roll the stand out into the main sho...

Now with new cylinder studs and threads repaired in the crankcase I chose 12 head nuts from an assortment of several. While spinning these onto the new studs I noticed a wobble in several of them. Not a good combination for torquing down the head properly. So I screwed these onto a threaded adapter ...

There's a bit of art in turning perfect threads on a lathe. I still enjoy reading old machine shop books that tell how to grind the tool, set the point and compound and so on. I'm at a disadvantage cutting metric threads on the big lathe as it is missing those gears. If I wasn't electronically chall...

The brakes are finished so I disassembled the motor. Starting with the head, 2 of the valve shim bucket were stuck in the head. Several hours of soaking with Kroil, heating and cooling and they finally cam out without damaging the head. The surface of the head was heavily pitted and after attempts o...

If you aren't over a hear behind that's a good sign I have stopped counting projects, now just counting years...left.

Looks nice. Who did the powder coating?

The sleeve is aluminum 2024-T3. 6061-T6 would have been ok too. I bored and reamed the piston and then turned the od of the tubing to fit using loctite. I finished of the bore off with a 5/8 reamer.
