Sorry for the hijack here, but this is What I've been tinkering with, Steve

Dude! I'm following this post. Wicked cool bike here! I'm liking how it's coming together. And you've got skills and an eye for re-purposing stuff. Can't wait to see the finished product.
 
What am I building?...Let's see. Toy..maybe.
Mental addiction..probably
The engineering equivalent of masturbation?
That was it! Now I remember. But most people just call it a "motor bike"
 
Heritic,

And what a sweet motor bike it is too. Keep sitting here looking at it and seeing more of what you've done every time I do.

Steve.
 
finally got around to the motor. Tore it down, soaked, scrubbed, blasted, and painted it. Replaced the carb, drilled and tapped a for a brass oil fill.( totally stole this idea, thanks who ever did it first. ) Cute little sight glass came off an old locomotive governor. Not sure if it will work on here but it sure looks nifty.


Once the paint cures I can toss all the itty-bits back in.

Also picked a new front hub, spokes and hoops.
 
Started getting my motor all hooked back up. With the new carb that meant running a new throttle cable, so apart comes the throttle. This thing took the better part of a month to machine, all the parts were made at least 3 times just to get them right but in the end I was very happy with it.
So in the interest of saving anyone a little time and frustration here's a few shots while I had it apart.



Cutting the helix was probably the hardest part, getting the right pitch, the right throw, and balancing the twist with the return spring.
If any one feels like trying to make one feel free to hit me up for advice.
As for the cable, that's all together and the engine sounds wicked good with the new carb.
 
Honda Cubs used to use that method, also some JawaCZ bikes, if you trip over one that's being broken for spares.
 
That's where I got most the concept, found an old part# drawing for a Cub then worked out the sizes to fit inside an old brass cutting torch handle.
 
I hope you've sorted the lubrication better than Honda, they can become very hard to operate when the grease wears off.
 
At the moment I'm trying plain old bearing grease, seems to work ok. After it was all back together I remembered I wanted to try lithium.
We'll see how it goes.
 
Came up with a brake lever off an old piece of equipment. That with some time on the lathe and some stainless hardware should work just fine.


I love the look of old crap mixed with freshly machined parts.
Just need a few 1/2" oilite bushings and to weld on some brackets.
