UPDATE:
13 motorcycle frames, 13 engines, 26 wheels
8 vehicles complete enough to be immediately recognizable as motorcycles
6 of them are titled
3 of them are registered/insured
AND STILL NONE OF THEM RUN!!!
For one beautiful day last week I had one bike that ran long enough to take me to work and back. Filled it up on the way home, parked, and smelled gas. Then I saw gas. Dripping. Fast.
Seam failed at the back of the gas tank
Meanwhile, I determined that the petcock on my SV was not functioning properly, but not until after applying way more vacuum than you're actually supposed to use on it. Which probably broke it. So, the new $60 petcock that I waited two weeks to get from an online parts dealer did me no good, and now I've got the carbs sitting on the workbench, next to three sets of CX500 carbs that have already been taken apart.
Edit to add- you really don't expect to see this on a bike that's never sat for more than two months at a time...
