My bike (2002 Honda shadow VT600) was running great, and then I let it sit for about a month. Now it starts up perfectly without any issues, idles for about 30 seconds, and then shuts off. Then it won’t start back up unless I let it sit for the night and come back to it. I have checked battery connections, charged battery, checked fuses, And replaced spark plugs. I don’t believe it is a fuel issue because I can see the carb injecting fuel when I start it up. It shuts off in a pretty consistent time frame. And for idling for only 30 seconds, the exhaust seems pretty hot. Any help would be greatly appreciated so I can stop losing hair over this issue. Thanks in advance.
