I have a TT-R 50 and it is a great bike but it is hard to start when cold and it seems to run rough above half throttle is there any one that has the same problem and how did you go about fixing it. It seems to be a fuel problem as if I turn fuel off it will eventually run better until running out of fuel I have had carbie off once to clean I am thinking of lowering the float level, so if there is anyone with information it would be greatly appreciated. Thanks Jon
