Rotax specify a full return system

Rotax have specified a full return system for all their engines and also a pressure relief system to protect their fuel injection system. Our V4 meets their demand and our new ‘slimline’ V9 will have an internal back pressure by-pass- the first valves to meet the new Rotax requirement- V4 are in stock and V9 will be soon (ish) in Summer 2017.
