Our initial testing showed the EFI 700 to work quite well in stock form. It did, however, have room for improvement.

Our initial testing showed the EFI 700 to work quite well in stock form. It did, however, have room for improvement. We designed a new primary spring and a custom-ground set of billet flyweights for this application, achieving much better belt grip in high range, less hitting of the rev limiter in loose conditions and more consistent RPM control with no loss of top speed. This kit engages right off idle just like the stock clutching and although drag racing results only show a slight advantage with this kit installed, (approx. one bike length in 400 ft.) high range is much more effective at lower speeds.
