I ride 2 strokes. Reliable as gravity, and cheap to rebuild every few years. Love it when folks twice my age on bike forums froth at the mouth when i mention using cheap conventional mineral oil that meets OEM specification requirements, chainsaw bar oil on chains and foam air filters, smoke pluming premix ratios, standard nickel-alloy plugs rather than iridium / platinum gimmicks, rider skill outweighs needle in a haystack tyre choice etc..
Best thing i ever did was discontinue employing Dell'Orto carburetors, and stuck with the "how far from 4 stroking" method by jetting overly rich so they fire on every 4th cycle until leaned out in small increments.. rather than waste money chopping a dozen plugs in half to inspect insulator color for safe a/f ratios.
