I am at the point in my dirt tracker build where I am fitting tanks. I found this Honda XL250 high tunnel tank in decent shape for $60 and hope to run duel fuel lines off it. The petcock I found has two 1/4” lines off of it but I am worried the 650 engine may outpace the supply. I have no experience to back up this concern and would love everyone’s input. Thanks in advance!

Unless you plan on setting a land speed record, that petcock will be more than enough.
Most likely more than enough for a LSR too.

I think when finished the Honda tank will look pretty smart above the XS motor. Although perhaps you could extend the back a bit so it can go further forward. The extension could be just a facade and need not hold fuel. A friend did that to a Tracker tank and it made the tank look a perfect match for the seat.
If you've ever drained a tank into a gallon milk jug, you'll know that the jug overflows in less than 10 min. That's more than 6 gallons an hour flow rate... and that's a single barb. Think an XS650 will ever suck down about two tank fulls in an hour?
Well, not a habit exactly but I went through filling jugs with petrol and timing the result to measure flow rates with the wee Bullet 500. The fuel tap that came with the bike gave more of a dribble than a decent flow, replacing it resolved the issues I had with the bike conking out.
