Product Details

K&L Air Cut-Off Valves are an inexpensive alternative to the OE assembly. They prevent afterburn generated by a lean fuel mixture when throttle is closed. Cut-off valve temporarily closes the slow-jet air passage, which instantly creates a richer mixture. High-quality kit contains only the parts necessary for a complete rebuild of one carb – diaphragm, spring and O-ring.

Will this replace the torn diaphragm in my 73 honda cb360?

Also, does the price include one or two?

BEST ANSWER: Thanks for your question! When you order the K&L Air Cut-Off Valve this would replace the torn diaphragm, these will be sold individually.

Exactly as Advertised
I ordered two as replacements for the rotted Air Cut-off valves on a vintage 31 year old Honda CX500. the order arrived promptly and dropped right in place with no modification or adjustment needed. The bike once again runs like new and I am more than pleased. Bike Bandit does it again - quality and affordability.

Highly recommended
Ordered these parts for my 1981 Honda CB750. Staff for ordering were helpful and knowledgeable, parts arrived in a timely manner and needed no adjustments or modifications to install. After synchonizing the carbs to the new parts, the bike rode perfectly in all ranges.
