So, this is my second year of karting, and i'm thinking of switching to the Rotax engine for next year. I've been racing 60cc and 80cc 2 stroke Comer (W) engines. I'm planning to get a 125cc 2 stroke Rotax engine. What is there to look out for with the Rotax engine? How should it be maintained? Is the electronic starter and wires waterproof? I would like to know anything about the engine.
