Can a kart radiator with a hole be repaired?

Despite what one might think, the construction of a 60 Mini engine crankcase is very complex even when looking at engines with less expert eyes. More than that of a KZ engine. The main difference is in the cooling fins, elements that have a heat dispersion task in a 60 cc engine. The fusion of these fins is rather complicated and requires more work, with a consequent increase in manufacturing time. For these reasons we can say that, at least as far as we at TM Racing are concerned, the 60 Minikart engine has a more complex crankcase than the KZ engine.
