Okay.... update.
Opened the float bowl drains and have a steady flow of clear, clean 93 coming out.
Compression check was fine.
I don't have a carb balancer atm, but I hooked up a vacuum gauge and I'm pulling 20hg at all 4 vacuum points.
Took apart the right side carb, everything is spotless. Took out all the jets. They're clear. Floats look fine, not full of gas or anything.
Hidden fuel filter is clean as a whistle.
With the bike running,I stuck a scope in the airbox side of the carb, started the bike and physically watched the slide actuate as I worked the throttle.
I Basically paralleled the spark plug circuit with a separate spark plug, thinking maybe the spark is breaking down under load. Not the case......
I'm really baffled here.
Help, please, anyone......
