It all started when I noticed that the low beam wasn,t working. Replaced the bulb now it turns on sporadically. High beam works fine, however, I was riding one time and I lost all lights at night, and quickly they turned on. The new problem. Bike starts fine, I start riding and the motorcycle stalls after a while, try to start with no success. It will finally starts again after 20 minutes later or so. Fuel tank full, oil within limits. I need some advise. Thank you beforehand.

The lighting problem sounds like a bad or loose connection or a bad ground.

The new problem is somewhat similar to a problem I had with my 2003 T100. That turned out to be a bad coil.

Thank you for the info. I will check the coil.

this isn’t happening directly after you wash the bike, right?

Following. I’d suspect the coil as well for the new issue. It’s sounds similar to an issue I’m having. I have a new coil on the way.

Could be the timing sensor causing the ignition problem. The sensor on my Bonneville was faulty- bike goes fine- bike stops- wait for 15 minutes- bike goes fine until bike stops etc. Easy job to replace. It is under the right hand side cover over the alternator and it is set with a feeler gauge. The hard part it figuring out the where the connecting wires are routed.

Reading this reminded me of the same issue I had with my 1966 TR6C. I went out one night for a long ride. On my way home I had to climb a rather steep hill. Half way up that hill the bike stalled. I could not start it again. I reasoned I might have been out of gas. I opened the tank and looked into the tank and saw I had plenty of gas. After a few minutes i was able to start it again. I had it stall on me several times after that. Each time I looked to see if I had enough gas. After a few minutes I was always able to start it again.
One day I was studying the gas cap and found the vent hole plugged. I cleared the obstruction and it never happened again. It may sound elementary but its the little things that drive us crazy. I think that as the gas drained out of the tank a vacuum occurred keeping the fuel from draining into the carburetor.

So often we overlook the easy fixes.

Let us know what you find.
Updating my ignition problem:

Ive ordered the maint book. and Started troubleshooting the Ignition coil along with the Camshaft position sensor. I measured the coil prior to starting the bike and it measured 0.6 ohm, this is within tolerance according to the book. Also, I measured the camshaft Position sensor, which showed some sort of measurement, however, the book doesn't show tolerance for it. I ran the motorcycle to make it stall, and I retook both measurements, and these are the results; The camshaft Position sensor gave some sort of reading, while the Ignition coil showed no reading whatsoever. I'm under the impression that somehow when the coil gets to a certain temperature, it stops working and then when it cools off, it works again, as when it's cool I got the 0.6 ohm again. Unless there is some sort of protection system, that turns the ignition coil to prevent engine damage, I believe I have a faulty ignition coil. I ordered one, I will keep you posted. Ive heard this is a common problem in the T100. However, if it is, is very annoying and the coil is about 160 dollars tax included.

Let me know, If your ignition coil was at fault, I ordered one as well.
