So if i go to start the bike after its been sitting a few hours it starts right up. Then about a minute later it dies and wont restart. I checked stator, new battery, in line fuses are good, the speedo reads random mph when revved in nuetral, theres some gas in the oil and a leaky petcock. The latter two issues I have parts in the mail to fix. I have checked for knicked wires or bad grounds and cant find anything. I also have checked the seals for intake and carb. The previous owner installed what looks like an e model tank with no visible vacuum hoses. Any guidance would be much appreciated.
