And there are 3 cylinders that have had the same gearing fitted as the 4 cylinder metro, and thus they have the SAME cruise rpm. And I'm guessing they cruise more efficiently because they are smaller displacement and have less cylinders.
Does anybody try to get the point. We are changing the gearing, or even the tires to turn the 4 banger motor slower. the same amount of cylinders is firing a minute. the reliability comes from a 4 turning at 2400 rpm and a 3 turning 3200 rpm. they are doing the same job but which would last longer. the effeciency comes from now turning the accesories slower like an underdrive pulley would. I do really like the destroke idea, along with the xfi cam (which would go in the engine evenwithout a destroke).
