No you do not have to turn it off.
Matter of fact if the bike is sitting for a while (week), the carbs will stay full of gas.
Evaporation will cause the float to keep filling the carb.
Some times when the bike is on the kick stand the angle of the bike can cause a float to
stick but it is rare.


Just be careful when parking a motorcycle in a garage that has
a gas fired hot water heater close by.

IF you leave the gas on and a carb has leaking fuel you better put some
new float needles in the carb before you have a fire.

If you have to let a bike sit for 60 days or more it is good to drain the gas out of the tank and float bowls.
The new ethanol gas can break down after 60 days and all of the moisture will go into the bottom of the fuel tank and to the bottom of the float bowls and cause lots of problems.
