I have a 2010 GSA. I've had the bike for 8 week and can honestly say its about the best bike I have ever had. It does everything I want from a bike and does it well. The only thing I would like to change is the flat spot in the performance between 5,000 and 5,500 rpm.I assume this is designed into the engine mapping for some good reason. My question is can I do anything about it?
