I found another bike I want...It is not a 125cc, and it isn't liquid cooled either, but it does have fuel injection! The Hyosung GT250R. It is a 250cc air/oil cooled V-twin with fuel injection(starting 2008). Despite being air cooled, it has a 10.3:1 compression ratio. The best part of all is that I found a bike I want that I can actually buy in Merica'! Unfortunately, there are reliability concerns, and of course I can't have three motorcycles either, so that's that.
Stock gearing appears to be very revvy, and it only has 5 gears, but there is a 1 tooth taller front sprocket available. I could get pbisprockets to custom make taller rear sprockets, or buy a blank from them and mill my own.
