Hello,
I am interested in what changes can be made to the standard Junior rotax engine and drive system. Can you use higher quality sprockets and chains, plugs, air filter systems. Is this against racing rules and are there any specialist suppliers that make bespoke components. What changes do people make to improve performance?
