About K&L Air Cut-Off Valve Set

K&L Air Cut-Off Valve Set

  • Heres an inexpensive kit as an alternative to the costly OEM assembly
  • To prevent afterburn generated by a lean fuel mixture when closing the throttle, the cut-off valve temporarily closes the slow-jet air passage, creating an instantly richer mixture
  • Included in these high quality kits are all parts necessary for a complete rebuild. (diaphragm, spring and O-ring)
  • Made in Japan.
