Has anyone ever had a problem with their sv650s dropping down to one Cylinder at idle. I have a 2005 and it has poor spark from 1-4000 rpms. I've taken it to a suzuki dealership and they gave me the run around just because I didn't buy it from them. This sucks. I love the bike buy running it sometimes just is awful. if anyone has any suggestions that would be great. They try clearing aut all of the fuel and replacing it. They checked the fuel lines and the air lines. Checked the battery, changed the sparkplug. Anyone know?
