My bike ran out of gas, I found out my gas gauge was off showing a half tank but looking in there it only had a tiny bit of gas. I tired starting for a long time before discovering it was out of gas. I put a gallon in it still no start. Cranked it for a long time. I checked the lines for and petcock for blockage and blew air into gasline to tank. Finally got it started after jumping the fuel pump to the battery. It took a few cranks but it started and runs. Im only getting 7-8 volts to the pump is that right?
