I saw a forum topic a couple of months ago about the flat spot at around 5000-6000rpm on the Hyosung GT250. It suggested cutting a particular coloured wire in the CDI. I can't seem to fing the posting. Was it on this site or another? Can anyone help? I am not very mechanical but I reckon I can cut a wire. The problem is that I don't know where the CDI is on the bike. Can anyone help with that one?
