Thanks for the responses. Let me describe in more detail what’s going on.
It may or may not start. If it does, it tends to run for about five minutes and then die. If it dies, or if it doesn’t start at all, I remove the spark plugs, wipe them down and put them back. It starts in most cases although sometimes not. Also, possibly related, is that the seal between the tank cap and the tank is worn. Some water might have gotten in the tank.
<quote>First of, does your RE have a carb or is it EFI twin-spark? If it's the latter, you might be having the side-stand kill switch that causes problems. It might be a good idea to disconnect the side-stand switch and try it out. These bikes can run on most grade of fuels but there is a good chance that the fuels in bangladesh might be 'spiked' with water..as you know, corruption.</quote>
It is the latter. Can you explain the relationship between the kill switch and watery fuel? Or, in the case of Bangladesh, it’s more likely to have been doctored with kerosene. Anyway, I don’t get the connection between the kill switch and the fuel. Also, although I did not remove all the fuel, I added a half tank and some octane boost. Would the problem persist for a few days and then go away? Or should I add more boost?
<quote>you should take it in to have the new map installed in the computer</quote>
I can’t since I live in Bangladesh and there are no Enfield dealers
<quote>The Bosch spark plug Royal Enfield installs for the US models is garbage. I don't know what spark plug you installed but if it is available try to find a NGK 6ES.</quote>
I’m not sure which plug but it’s not the Bosch. Might it be that my plugs are “running cold” and that I need a hotter running plug?
