I was asked to start our own thread on this topic. Last year we bought an SDS fuel injection system after many high reviews of the product.

The system will ballpark cost you about $3000-$3500 for the Rotax. That includes everything you need.

The system gets you 10% power or 10% more efficiency. Or a combo of less of both.

Due to my obvious lack of time in the past two years, we haven't hooked up the system fully and have not ran it. Scott Noble may chip in here as he is looking at the same system.
