Help! Running rough from bad gas
I hope this goes in the Service section.
Two tanks ago I had taken a long day ride to visit some friends. In the evening I filled up the tank, and immediately the bike began riding rough, but it was more than rough. The bike hesitates, hiccups, stalls, chokes itself and various other nasty things such as get 75% of the normal gas mileage.
I've ridden through most of that tank and filled it up again. Towards the end of the first tank it appeared to be running better, but after filling it it got worse.
One thing that has gone away is the choking. Before, when I gave it gas, it might actually slow down. That happened to me once in my old truck when there was water in the fuel filter. But Vstroms don't have fuel filters - and that has gone away.
Now, if not warming up or twisted throttle the bike stalls very quickly. I'm getting towards the bottom of the second tank. Should I just empty it? How will I know if the bad stuff is gone? How can I drain it?
Any other advice? This has become very annoying, and I'd like to get my old bike back.
Thanks in advance.
