Slinger Airflow Werks 40mm CV Vacuum Piston SAW-018

I only needed the diaphragm for my 97 sportster 1200C, and this was the best price for just the diaphragm. Other places only sell kits and the needles are not OEM for my carb anyways. Came in brand new condition, my old piston had rubber flaking off the sides and small holes in it. If this is all you need to buy it from here.

I have a Kawasaki KLR650 with a Keihin CVK40 carburetor and this is every bit as good (if not better) than the stock part and less than half the price of the Kawi part. It fit perfectly and solved my problem with a torn diaphragm (I couldn't accelerate past 60). If I am unlucky enough to have to buy another, I will certainly buy this one.

Works great on my 2003 Super Glide

The previous owner of my new/used 2009 KLR650 had pinched a hole in the diaphragm. This replacement was 1/4 the price of the Kawasaki part. It works just like the original.

fixed the sputter at idle and cruises fine.

I was really surprised at how quickly I received this product. looked well made and when installed in my carb. performed very well. Couldn't be happier

Fast shipping, fit perfectly. Nice replacement for the factory one. Haven't had any problems since I have installed it in my bike.

Worked as a replacement for a KLR 650.
