Can this Ball Joint Conversion Kit (Part # 15-04939) be used on the Rotax 503 engines also? It only calls out Rotax 912s but I need two of these for my 503. Any help would be appreciated.
No, but we do carry a conversion kit for the two stroke engines, such as the 503. The part number is 15-07409. It is the same thing, only for two stroke engines.
