When motorcycle is not running, fuel shutoff valve should
always be turned off to prevent possible leakage should
needle and seat not seal completely.

Gasoline leaking past inlet needle may flood engine causing
contamination of oil supply and damage to engine.

Any gasoline leak constitutes a fire and health hazard.

Throttle plate and throttle shaft should be checked
annually for signs of wear. Replace if necessary. If carb
body throttle shaft bushings are worn, carb must be
returned to S&S® for repair. If throttle plate removed, be
sure to reinstall correctly. See Figure B. Beveled edges of
plate must fit flat against carb throat.

If accelerator pump cap is removed, lift cap slowly so small
spring check balls and o-rings are not lost.

For racing, S&S offers two air horn conversion kits which
include appropriate mounting hardware and a substitute
enrichment device. One includes a 21⁄2" air horn and the
other includes a 4" air horn.

If fuel delivery from stock petcock appears insufficient, S&S
recommends that a high flow performance petcock be
installed.
