Relative got a kawasaki 110 in a divorce and the jagoff put sugar in the tank before he gave it to her. I cannot seem to get it out. I haven't used antyhing but gas. Should I remove the petcock and rinse it that way? He said it wasn't started and the gas never was on. This was after her son wooped his arse.B). What is the best solution- replace tank/or is is salvageable. thanks
