Fuel tank, 84 miles, 2 more gallons?
PROBLEM
Second.
Wouldn't start added 2 gallons and then it did start. I'm guessing it wasn't full after the 2 gallons?
Is fuel getting past the petcock while bike is off?
Service manual has procedure for setting float level and inspecting needle and seat for wear.
Prolly do that before starting to throw parts at it. Choice is yours though
Oh! You are new parts? Did you set per factory spec? service manual and youtube are your buddies!!
Mine seems to love to leak a little from the valve clearance access plates and the head gasket.
New head gasket seems to have fixed that leak but I used gasket sealant for the access covers.
I'm kinda wondering if your motor oil in the case has a gas smell to it...
