My rm 125 has been leakin gas when i leave the gas on and its because the float height is wrong. when the bike is off the float doesn't shut off the gas so it leaks. what i need to know is the height so it will work properly.

Are you sure it is the float height or is the needle/seat worn and need replacing? Don't have our manuals anymore but if I recall correctly our 05 was 8.7 mm.

do it by sight. no need for any spec or measurement.

Also with the new ethanol fuels, it can eat certain rubber especially on some float and needles. So you may need to replace the needle/seat
