Been slowly working out the kinks...
Yesterday I went for a ride into San Francisco. As the highway ended and became urban, I realized my throttle was stuck open (extremely high rpms). With the help of the kill switch, I pulled over, kind of sorted it. Then it happened again. That time I found the root cause. The "B" or "safety" cable was loose at the carb end, and it's housing was actually holding the carb open a bit. So, I just removed it for now. I need correct length cables for my setup.
Then, on the way home, just as I got done with some highway miles I came to my first stop. Now the bike wouldn't shift into 3rd. I made it the few blocks home. Luckily, it seems to have been a loose bolt in my shift linkage. Shifted fine after that correction.
Today I performed a vacuum sync of my carbs. They were way off. Now spot on.
Finally, I think I have a little bit of the old "hanging idle" problem (slightly high rpms). Sometimes she races a bit when I get to a stop. Then I can sometimes get her to settle back down. I'll look for an intake air leak next. With new boots and o-rings installed, it seems unlikely to be more than an assembly problem if that's even the cause. Otherwise I'll keep looking.
I'm definitely having fun out riding! And it's kinda fun to work through all the little things. It's a great feeling to have built the bike myself, so that if anything breaks, I know how to fix it.
Cheers,
Dave
