New to 98 Valkyrie Stranded on the way to work. Suspected Fuel Feed problem

[The emperor has no clothes]

I would make sure your tank is vented properly. Check the gas cap. Mine died on the freeway on day and after opening the cap it started and all was well. I found that my tank bag was pushing down on the cap.  Never happened again.

On this issue a roadside fix is put a penny under the cap.  If it is the problem, when it stops, on the side of the road, put your ear next to the cap and open it - you may hear a whoosh when you break the seal.  BTW that hose is not needed for the bike to run. You can shorten or remove it - potential problem gone.

The fuel line must be level or downhill - any uphill segment will produce the problems you are having.

A bad petcock can be eliminated with a Pingel.  A vacuum problem can be eliminated by making the OEM petcock manual.  A leaky petcock - Pingel again.

The bike won't tolerate a filter on the fuel line.  I have tried 3 of them, even ones made for gravity feed fuel systems.

Have addressed all of these problems with 4 Valkyries.

I wouldn't recommend removing the vent line. I've had my tank full sitting in the sun and had it gush out. It's bad enough to have 1/4 gallon of fuel on the asphalt below your bike. I would hate to think of all of that dousing the bike.

What about vapor lock? When the engine heats up the fuel lines causing an air bubble in a line and blocks the flow of gas. Red eye makes a heat shield that goes on top of the engine just for this. Kind of a shot in the dark. Will be interesting if this stops in cooler weather.

Don't fill the bike full if you aren't going to ride it right away - especially on hot sunny days.  That goes for whatever kind of vent line you have.  You should have learned that after the first time you had it gush out.  I never top it fully if I'm about to park it - and always eat the lunch first, then go get the gas. We have INTENSE sun out here at high altitude - everyone in Colorado who rides learns this one right away.

Not necessarily ignition related.  The op has no clue about where to really get a start on this.  Fuel leak aside this a a classic petcock problem.  Diaphragm is leaking and now not enough vacuum produced  to let fuel flow.  He needs to install a new cover set and before attempting to start, apply vacuum to the petcock to fill the bowls.   Why he won't accept a bit of help from an experienced valk owner living so close is something I don't understand

Some people are just plain stubborn

I wonder if he ever got it fixed?
