Default Totaly stumped on new engine issues/symptoms

Today I took the bike out to a doctor appointment so I could conserve what little gas remains in my Buick. On the way back the bike cutout completely 3x like it ran out of gas but I know I had at least 2 gal remaining and it only 20 miles to the appointment. I restarted each time started fine but every time I got over 40mph it cut out. I finally manage to get home and park the bike. Then went to take an hour nap before work. (I have the stomach flu and was up all night Mon morning tending to the nasty stuff that goes with it.) About 30min into the nap my wife informed me that there was a large pool of gas under the bike. I went out side to check it out and couldn't figure out where it came from. So do you thing this is related to the Intake Manifold mentioned on my earlier post?

I couldn't find any earlier posts about a manifold. Where is that?

Float in carb is sticking from dirt or whatever is my guess.

Check your fuel line, when it gets old, it will start to crumble from the inside out and that junk has to go somewhere...right into your carb and float needle.

Not sure what issues your having with your intake, but fuel air mist is the only thing that should be going thru the manifold.

The puddle tells me the your float is sticking from either debris on the float needle and or seat allowing fuel to keep running into the carb and out the over flow.

Do you shut off the fuel at the petcock after a ride? YD

As YD suggests, the pool is caused by not turning off the gas tap, but the main culprit is likely to be a dirty fuel bowl in the carb. I suggest you get a carb overhaul kit, but also drain the tank and clean it and the gas tap, just in case there is some crud in there.

+1 for cleaning the carb and replacing the fuel line.

And if you have a vacuum operated petcock, you can assume it's bad.

my guess is the ignition trigger in the cone has been over heated and or the new one is bad - when it gets hot it cuts out - wait a couple mins and it starts back up and runs for 10 more

For the fuel issue, yea a rebuild. Make sure your kit has a brass needle and seat for the float the aluminum ones suck...

The way I read the original post the bike would stay running until he got over 40mph.
Would that also indicate a failing ignition trigger?
I thought when they failed it was because of heat not speed.
