JBM Industries

If you have 38, 36, 34mm Mikunis on your bike and your slide diaphragms have seen better days you need to check out JBM Industries and pick yourself a new pair. I have shopped around and for the money you cannot beat what they are offering @ JBM. I needed a set for my 1978 XS500 and after doing a bit of research I stumbled upon JBM site.
You can pick up the complete slide and diaphragm set at MikesXS for $69.00 a piece. Speed and sport carry the assembly for $97.00 a piece or this guy sells them on ebay for $49.00 a pair.
After checking out the other guys, I came to the conclusion JBM's products are by far the best option for replacing your worn out diaphragms. They "started in 1978 making reproduction rubber and machined parts for vintage automotive hydraulic systems.
JBM is unique in that we offer both design, development, and manufacturing of many hard to find or obsolete mechanical or rubber parts.
Being small offers us flexibility and the ability to offer attention to detail. We solve problems here. JBM strives to make better quality parts. We are not always cheaper, but in many cases we are both cheaper and better than other manufacturers. We design and build our own tooling, or can run your tooling in our shop".
They also make carb holders for the same size carbs I mentioned in the beginning of the post. The installation of the diaphragms could not be simpler, and they have detailed instructions on their site.They also make diaphragms for KZ400's and 440's with Keihin CV's. Or if you need some for the Hitachi HS32's on your Maxim or Seca, Jbm is your one stop shop.If you can't tell by now, I am very satisfied with the product they offer and think you should run over there and get yourself a set whether you need them or not. They do make nice knick knacks and would look nice sitting on a shelf next to all your softball trophies.

Till Next Time.............
