I see you say it won,t run after 5 minutes... if you leave this line off of the carb... will it run for more than 5 minutes... if no... then I would check your fuel cap for venting ... to let air in to let fuel flow to the carb... there is a vent hole in the cap or at the top of fuel tank... leave the cap off.... let it idle to see if it shuts off... or only have about 1/4 tank of fuel. and ride it without the cap ... or have the cap not tight... to let air in... this might be the problem for running.... that and too much oil... and not venting... and maybe the blowby problem of rings not sealing yet... how much blowby air comes out of the hose.... much???
