This is a brand new set of four carb insulator boots (also called holders) for the 1987 VF700C and 1988 VF750C Honda Super Magna motorcycles. These are the rubber parts that connect the carburetors to the engine's intake ports. Over time, the originals can crack or harden, causing air leaks and rough running - replacing them can really smooth out your bike's performance. These are made in Japan and are direct replacements for the original Honda part number 16211-MB0-000. They come in original packaging unless noted otherwise. Country/Region of Manufacture is the United States (likely assembled or packaged there). There's no specific warranty mentioned, but as a new part, it should be defect-free. Compatible year is listed as 1988. If your Super Magna is sputtering, has a high idle, or is hard to start, these boots are a common fix. A must-have for any vintage Magna owner doing a carb rebuild or tune-up. They ensure a proper seal so your fuel mixture is right. Get your classic Honda running like new again!
