Pretty much. While they are not the peak of technology anymore, they were becoming very well engineered and sophisticated towards the end of the 2 stroke era. Advanced metallurgy, oil and fuel injection, etc.
A piston and pot with gasket set are usually reasonably priced if you need it, but I would just run ‘em ‘til they quit, then worry about repairs.
yep, about $180 for a 2-cylinder kit / $260 for a three cylinder.
Reasonable.
