With debugging the wiring and ignition done, attention turns to getting the fuel in. The carburetors on this bike are pretty sophisticated. It costs $135 in gaskets and o-rings to rebuild the entire thing. It takes about 3-9 hours to do the whole thing right. There are a few people who do the rebuilds and will charge you anywhere from $200 to $800. The turn around time is anywhere from 4 weeks to 3 days. That's an option for some people, but anyone who claims to be an engineer should have no problem performing
this rocket surgery. So at the least, figure it costs about $150 and at least a whole day of work. This particular set wasn't completely filthy like some I've seen. Now that they are rebuilt, the engine fires right up and idles nicely.
Rebuild kits:
One of the float bowl screws had stripped the threads right out of the body, so I tapped it oversized and cut a new screw for it. Fortunately nothing else needed any machining or otherwise modifying. I could have drilled out the jets by a few thousandths to allow for extra airflow, but that isn't in the plans yet.
I found this micro lathe and have it kind of set up for drilling stuff. Its more of a novelty at the moment because the drive system is kind of scary and I'm not sure if the leather belt drive system is usable. The drive motor sounds like a jet engine spooling up, but fits in the palm of your hand. But it is the smallest useful lathe I've ever seen. For $40 at a garage sale, so beat that.
