Uncle Mike's BIKE Dead on Chicago Expressway - Coil question

[UncleMike]

I was running my XS400 at WOT on route 17 outside of Bath NY a while ago into a really strong headwind, so strong I couldn't get the bike over 80 and it actually cut out until I backed down to 65.
I think the petcock lost vacuum and cut off fuel. I had plenty of gas so I went to PRI and took it back up to 80 and it stayed there.

You may have had the same thing happen if it was running wide open, a loss of manifold vacuum on the petcock valve.

Sounds likely, although that definitely wouldn't account for the issue that put me on the side of the road during rush hour in Chicago.

Sorry Mike I didn't see this until today...
Amy took a bunch of pictures at our place Sunday...I'll pass them to you tomorrow...

Great! Thanks.
