Cylinders are back in stock.. double the price... Not sure if there different from the original... The problems are from the rings and bearing the piston casting... The ring pins... Not the cylinder itself... Just because someone sells something doesn't automatically make them the ultimate knowledge of everything 2 stroke... I can't be the only one who sees through this... If this was true every new and used car dealership sales team would be winning nascar racing with no competition...No aftermarket would exist and the billions spent would be for nothing... And forums like this wouldn't exist...
