Product Details

Air Cut-Off Valve Kit by K&L Supply®. Here's an inexpensive alternative to the costly OEM assembly. To prevent "afterburn" generated by a lean fuel mixture when closing the throttle, the air 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.

Notes: Not used on XV750 California model for 1988.
