Hi, have a problem with my 2010 Vulcan 1700 Classic Lt and wondering if anyone had simular problems. On my last ride I noticed my gas mileage more than doubled to 15L/100km. Bike seemed to run well at highway speed but at low speed it felt like it was only firing on one cylinder and ran rough. When at idle the RPM's would go up and down. Eventually the bike stalled and would not restart. I checked the oil and found the crankcase filled with gas. Any help or suggestions greatly appreciated.
