    Anyone purchased JBM industries Carb boots

    I am looking to replace the intake boots that attach to the head. I will be putting them on a 81 Gs1000 engine and they have a set of 4 for $74. I can get some on ebay and or Z1 but they are $125 on there. I was wondering if anyone of the forum has tried these. A friend of mine has purchased a set for his XS650 and they are very well made. Their vacuum diaphragms they make I have put in a set of VT700 carbs and those are better made than OEM. Thoughts anyone?

      I haven't used them but based on feedback I've seen on their diaphragms I wouldn't have an issue with using them...

      For info I use the Z1 aftermarket carb boots on my 78 GS1000 as they are about half the price of stock & they are great but they won't work for your later carbs.

        $74 for 2 isn't it?



        I might be missing something though?

          you might be right on the price for pair. I will have to call them and find out. There is a guy on ebay selling a set of 4 for $85. I did look at the Z1 boots, they want $125 + shipping for theirs
