Every time I get done riding my 1978 kawasaki kz650 B2 it starts to leak fuel. It is not a constant pour, but about every thirty seconds it drains 2-3 ounces. Any ideas of what's wrong?

Fuel line may need replacing. Two-cycle fuel/oil mixture is very hard on fuel lines. It's the oil that really deteriorates tubing, even Tygon F4040A Fuel and Lubricant Tubing.

At each port there is a black rubber nipple hanging down that when removed allows you to drain excess gass before storage. You may check to see if one of your nipples has fell off.
