Hi, I'm new to the forum and have just started working on a 1995 KLR 650 with 2,200 miles. It looks like it sat for about 3 years with half a tank of gas. I have the tank off and have been trying to flush it. There is some surface rust in the tank, any suggestions how best to clean the tank for no problem future running. I assume the gas drain point is higher than the bottom of the tank? Will any sediment just sit in the tank. Open to all comments.
