Had to ask. Just remember this though...Even if it had gas in it when you got it doesnt mean its good and clean. Fuel can make varnish lines and scum that sticks to the tank walls and settles to the bottom as well. If i get a bike and theres gas in it I first drain it. Then I swish a quart of Acetone inside for a good while and let it set..then more swishing. The acetone breaks down the scum and rinses it out.
I use 2 inch green painter tape to cover the tanks if the paints good so the chemicals dont ruin the paint. If its gonna get repainted I dont care if the acetone splashes on it. Point is to be certain every component in the fuel system is for sure clean and free of crap that can break off and migrate down stream to the carbs.
VERY IMPORTANT!!!!! Dont rinse a tank with the petcock and /or fuel sender unit in the tank. Remove them, make some metal covers and gaskets. Then clean away.
