I had a 76F that always died at the same stop sign, two blocks after I went through a railroad underpass. The underpass was kind of fun, it had a downhill left turn then a sharp right, through the short tunnel then a quick left and back up the hill. two blocks later it would cough and die. I would walk it around the corner and give it a minute then it started back up and ran fine all the way home.
I told my mechanic friend, he said don't go that way. I thought the turns followed by throttle application going up the hill might have stirred up something in the gas tank. Anyway, I removed the inline filter and sold the bike to a guy that doesn't live near an underpass.
That one reminds me of the guy who came by one day, complaining that his new fuel filters "must be causing trouble somehow" on a 2-hose petcock 750K3. What he'd done: cut the hoses and inserted the 2.75" long fuel filters. I could tell the hoses were kinked up under the tank, so I asked him how much he'd shortened the hoses and he said, "I have to do that, too?". He said he didn't shorten them 'in case he wanted to go back to stock' again.
That one still puzzles me.
