Update- Confirmation on the bad fuel. Phase seperation. New filters (3) plugs (old plugs looked great), complete service, drained the fuel tank and in fact are replacing it entirely along with new fuel hose and primer ball. Burned the skimmins in the Snapper rider.
The VST on this Yamaha is buried behind the intake. Noone had the gasket or the filter for the VST. I suspect the injectors are full of crud but it may survive without taking it all apart. I mean that is a lot of filters. New tank, fresh fuel, ring free and stabilizer then a fuel pressure test.
