looking sweet have a look at mine http://www.scootershack.co.uk/threads/my-honda-cbr-125-r.31585/#post-298006
coz with a f,i you dont need to mod the carb if you put a different exhaust on it because the computer that moniters the amount of air to fuel ratio adjusts it automatically where as you would have to replace the main jet in a carb version
nice bike had the 2011 cbf not so long back and ive had a cbr, looking at getting another cbr now the computer adjusts the air to fuel mixture but if you change the exhaust to a aftermarket one you need to change the gap on the plug I think, what I was told by local bike shop anyway. did you consider a cbf?
I had loads of 125's in my time. I've had a CBF was really good but then I sold it for the Piaggio then the CBR lol
