On my GT, the bike didn't run very well until the updated the software to 4.10. I think you should really push that issue.
I don't see any problems with lights flickering or a low idle. It runs good now once it's warmed up.
When I first started having problems with the GT at Laguna Seca, I asked if there was a throttle adjustment. Joe (messenger13) told me he didn't think so, and the dealer confirmed it, so it's gotta be in the software.
When a government takes over a people’s economic life it becomes absolute, and when it has become absolute it destroys the arts, the minds, the liberties and the meaning of the people it governs.
