So I have my J-Model idling perfect and revving for as long as I want on the stand but when I start hitting the road about 2 min into my ride it bogs down and stalls, after I wait for about a min and start it up again im good for another 2 mins.

Does anyone have any ideas? The engine is a newly rebuilt stock with a carter N carb.
 
If you take the fuel line off at the carb and let it drain into a cup, do you have more than just a trickle? I have had a dirty sock on the petcock cause something like that. I'm sure you'll get some more qualified replies, but that was my first guess :)

Yeah, pretty deed here lately-
Anyway, when it dies, is there any sputter, or is it like somebody pulled the plug?
 
I saw an interesting response to a similar question online-
Here is what was suggested:
Carry a spare spark plug with you on a test ride.
When the bike dies, quickly slave in the spare plug then test against the crankcase for a healthy spark. This might help to at least eliminate one possible problem.
Regardless, I would swap in a new plug just to eliminate that since it would be cheap and easy :)
Good luck with the diagnosis.

You could be filling up the fuel bowl by letting it sit and then when you go for a ride you use up the fuel in the bowl and it dies.

To test: Let bike sit with fuel turned on and then start the bike then turn fuel off and go for a ride. If it dies in the same amount of time the problem is in the fuel feed.
 
Make sure your gas cap is still venting. It almost sounds like it is starving for fuel. A gas cap that is venting too slow will cause the same symptoms.
