Hi.
I have a curvy sv650s, which until recently would start first time at the first touch of the button.
On sunday i went to start it after a short ride and it would turn over but wouldn't start on the first try. I turned it off and back on again and it started fine. I then rode 10 miles and it ran absolutely fine.
Stopped for fuel and after this it wouldn't start, same deal, turning over but not starting. It eventually went after about 15 minutes of trying.
Since then it has been starting only after trying a few times, and doesn't seem affected by being hot or cold, but does SEEM to only start when the bike is upright although this might be a coincidence.
When it does start, it idles and runs like normal.
Thanks in advance.
Ed
