I have a 2000 F4 and installed a dynojet stage one jet kit and i need to adjust the fuel mixture screw on the bottom of the carbs. The only problem is that the tool that comes with the kit is too big to use with the carbs on the bike which is where it needs to be done as the bike is running. Does anyone know of a good way to do this or a special tool that is available? Any help would be appreciated.
