I don't believe there is a such thing as a leaded fuel engine. All gasoline is unleaded, some just a higher grade.
leaded fuel is economic compared to unleaded because more distance is covered with leaded than unleaded
Unleaded fuel should always be used in a modern engine. Leaded fuel causes a detrimental buildup that will quickly destroy your bike.
Unleaded fuel was introduced in the mid 1980s, it depends what engine it has, if it needs leaded fuel you will need a new engine
unleaded fuel
No, it will mess the engine up
It won't hurt the engine but it will hurt the catalytic converter.
try a mixture of half leaded and half turpentine substitute i used to use leaded, but then decided to give unleaded a shot, works better for me, and had the engine checked.. No damage
Unleaded
leaded fuel contains lead which damages the engine while unleaded fuel contains negligible amount of lead.... on older engines the lead in the gasoline was to lubricate the valve stems in newer cars they have designed that requirement out
Why would you do this? This is difficult to do by accident as the filler nozzle, through which unleaded fuel is delivered, and the filler pipe on the car are both narrow. The wider nozzle used with leaded fuel and diesel just will not fit. Leaded fuel will quickly destroy the catalytic converter and O2 sensors. What other damage will be done is hard to say. Use unleaded and forget leaded fuel.
the 69 used leaded fuel, you can get the heads redone and have hardened valve seats installed and you can use unleaded with no problem.
