This question already has an answer here:

I purchased a brand new Royal Enfield Classic 350 yesterday. This morning I rode it to my office (around 20 Km), parked in the basement, and in the evening I started to ride home.

After 10 Km the engine stopped while running, so I pulled over and checked the fuel. I had filled the 2.5 litre tank this morning.

I tried to start again using the self start switch. It was turning over but would not start. The Amp Meter needle was touching the left side of the green area.

I'm unsure what happened to this new bike, so after noticing the engine was very hot I waited for 5-10 minutes and started again. It started, but after 5 km it stopped again. It did the same again after waiting for it to cool. And by repeating this process I got home.

Why is this happening to my brand new bike?

The Royal Enfeild is a very old design. The motorcycle is based upon an old British design from World War II and has changed very little over the years. I do not know what type of quality control process the Indian manufacturing of the vehicle has implemented so that is very difficult to asses.

It sounds like your gas cap vent or your fuel tank vent is clogged

What you are describing is making me think that your fuel tank is not allowing atmospheric pressure into the fuel system.

Your gas tank has a vent that allows the negative or positive pressure out of the system. You may have a kink in your ventilation hose. If the gas tank ventilates to the atmosphere it may have blockage there.

There should be a vent hose that is routed all the way down to the bottom of the motorcycle. It would route behind the engine. This tube cannot be kinked.

Symptoms

The symptoms of kinked fuel line will be stalling after the engine runs for a period of time and consumes fuel in the gas tank. As the fuel is consumed the fuel level will drop in the gas tank. The dropping fuel level would create a negative pressure inside the gas tank. The vacuum would prevent fuel from flowing into the carburetors making the engine stall from being fuel starved.

Find the vent hose, you may need to take the gas tank off the bike, and ensure it is properly routed. If you find a kink in the vent hose, un-kink it and make sure that when the fuel tank goes on the vent hose doesn't get folded in half.

This may not have anything to do with manufacturing quality. It may have something to do with how the bike was assembled.

  • Thanks buddy for you answer, every time I got above problem , I opened the fuel tank lead and shake the motorcycle to see if any blockage on fuel entry , may be this is the reason bike started after that. – Bharav May 9 '16 at 18:09
  • It could be. There is not a lot of information in your post. I may not be correct. I'm just answering from what I have experienced before. Good luck to you and perhaps I am correct. Please feel free to ask more questions if you need more help. Again, good luck and cheers! – DucatiKiller May 9 '16 at 18:12
