Two part question:

First of all, I was riding today and my baby stalled out. i've cleaned the carbs a while back and its got a brand spankin new por-15 coated tank with an inline fuel filter (k&n). i was riding and switched to 3rd gear climbing a small hill and it bogged down til i pulled the clutch in and it just died. i try to start it and it just turns over. i hopped off and pushed it to the gas station and checked my tank, full. i look under the tank and one of the drain tubes was pinched so i take it off, switch the petcock up reserve and choke it and it starts back up. and i ride it to work. was the pinched tube my problem for the tube?

Main problem: My problem comes around 4500rpm (cruising rpm) it feels like the bike is running out of gas and i can feel it hesitate ever so slightly. but if i roll on the throttle it goes away until i come back to cruising it goes back to feeling like its running out of gas. any ideas?

 

There should be two fuel lines under your tank. One is a overflow and the other connects to your petcock.
If your fuel line on the petcock is pinched then it will not allow the fuel to flow. Thats why you have to
give it more throttle to keep it running. If that does not fix your problem check your petcock and fuel
strainer for any clogs.
