Sounds like you ran out of gas. The bike needs a certain amount of air and gas mixed together to burn properly. When the engine is cold, the choke is designed to cut off the air supply so it's pure gas being ignited and you get a better chance of a good start. Once it warms up to operating temp, you cut the choke off introducing more air into the gas.In this scenario, it sounds like you ran out of gas on the road. You probably got a little spark when you choked it because there might have been a few drops in the tank but not enough to actually go anywhere.It doesn't matter if it's 85 degrees out or not, your engine still has to warm up. It won't take as long to warm up but it does still have to.Sometimes a bike can have some gunk and debris in the bottom of the tank. If you run really low on gas, that junk can be sucked through the fuel system causing problems. If you fill the tank and still have trouble, clean the entire fuel system.
