12.9 before starting bike idled at 3500 4000 RPMs not idled but running a 3500 4000 RPMs charges to 14.7 when I go for a ride it dies now within a mile seems to me either air or a gas problem cuz I can continue to turn the bike over but won't start some tobacco Park tomorrow has new fuel filter and new fuel pump and just start with a fuel and air any suggestions thank you for your time and concern

Sounds to me like a fuel supply issue. You need to check the fuel system from beginning to end. Start at the tank. Tank clean? Fresh fuel? Petcock working? Fuel lines clear? Filter clear? Pump working? Carbs filling?
Once this all checks out, you will need to thoroughly clean the carbs and reset everything to stock settings. Verify that the float valves are not leaking but are allowing proper fuel flow.
Does it start up cold easily?

Maybe when you ran out of gas, one of the floats got stuck or jammed. Just something to check once you get down that far.
