I believe I've got contaminated fuel in the Bandit. I don't wish to disclose how I got contaminated fuel in the tank as I would be in the running for some shameless & wanton stupidity award. If I siphon the remaining fuel out of the tank as best I can and then fill it up with new stuff is that likely to help matters, or will I have to change the filter, clean the lines and get the carbs flushed out?
