For the very first time my bike refuses to start. A month or so back she started to run a little rough and the plugs were a little carbonned. No big deal, I figured I'd get her tuned...however, my son arrived a little earlier than expected and I haven't been on the bike in a month. The weather here is very hot and humid (South Korea) and I suspect the heat has evaporated the fuel from the line, so I let the starter go for a good while....still nothin. Not even a whimper. Full tank of gas too.

Any tips?

What bike is it? I trust you have checked the kill switch is on, fuel turned on, etc?

Honda CB400SF, 97

Yep checked the kill switch and fuel.
