Yes it can be a possibility on a new vehicle. Sometimes there are problems in the manufacturing process that are not always found by quality control.

asg, even new rigs have problems.

A few things to check:

Blockages in the fuel lines
Blockages in the carb needles

Check the tank for air leaks
Check the engine for air leaks

Check fuel lines for damage
Check pressure line from tank to carb for a blockage

In some cases, a blockage in the pressure line can cause a suction at the tank pulling fuel back from the carb to the tank.

Also, try putting 2 o-rings under the forwards end of the tank as was suggested before, it may be that at half tank levels, the engine is not getting enough fuel from the tank due to the filter sucking air as well as fuel.

With the t/t tanks, there is a dodge to the filters, but it takes patience, time and a little intricate work, but it stops the leaning you get at half tank condition.
