Best of luck . The early 20s overheat under heavy load because of a small heat exchanger. Beta say not. But later engines have a slightly bigger exchanger. Wonder why.I love my newish Beta 25 with its high rise exhaust. However I will be checking its fidelity in future to guard against unexpected partings!
Has anyone contacted Beta about this matter as failure after so few years suggests some kind of manufacturing deficiency
