Question about 1982 Yamaha XJ 650
Hi i am having this problem with my bike recently. the bike starts fine and i was able to drive it for about 15 to 20 mins before it suddenly wile seaming to run fine the thing shuts down with out warning and backfires like crazy, now once i am on the side of the road the bike will not start no matter what. i unplugged the fuel like line to see if it was getting gas and it was poring out of there so it was getting gas. however once it sits for about 20 mins it starts just fine and runs like it should till it does it all over again and again leaving me stranded making wait 20 mins before i can go anywhere to only drive for about 15mins to get stuck again.
Check your ignition coils. Sometimes they fail with an open circuit, this can sometimes close up when the machine is cold and open again when it heats up. So. it will start when cold and fail when it warms up.

SOURCE: running problem
It takes electrical power to run the ignition system on your bike. If your alternator is not providing that power it must come from the battery. When the battery is out of power, the bike dies. You have a problem in your bikes electrical system. MOST likely is a faulty battery, but could also be alternator or other piece in the system.

Several things can cause the problem. First, spring for a new spark plug. The stock plug is NGK CR8E. Now the plug is eliminated as a problem. Next, pull the slide out of the throat of the carb. Now remove the jet needle. Put the needle clip on the 4th notch, (this is the stock setting). Use only premium gas. Next, follow the starting instructions below.
There is a proper way to start the engine. Four controls are on your bike to assist in starting.
This will likely tame the beast for you. Please rate this answer. Thanks!

1. Your float needle is leaking (most likely). Remove the carb, remove the float bowl. You will see the float itself and it has a tang that touches the float needle. Remove the float and inspect the needle and its seat for dirt or wear. You could try gently tapping the float bowl first, as this may dislodge and dirt, but thats a short term solution.
2. The float level is incorrect. You will need to bend the float tang to adjust. However, find out the float height for your bike first.
