What spring are you talking about? If you're referring to the small one the instructions show between the end of the clutch cable and the clutch actuating arm, you don't need it. In fact it will only make you clutch lever harder to pull and serves no other purpose. Do not install it.
The larger diameter spring, about 1/2", is a heat shield to protect the cable housing from the cylinder cooling fins. That one should be there but not essential if the cable housing isn't resting against the fins.
