JBM Industries in Kent, Ohio makes many innovative machined and rubber molded parts of high quality. The parts
offered here are manufactured by us right here in Kent, Ohio, USA
While we are mostly known for our long lasting rubber parts for Rotax, & HKS engines used in light sport aircraft
and ultralight aircraft, we make other parts, such as vibration Isolators, gaskets, and stainless steel exhaust springs
that fit specific Rotax applications.
If you own a Rotax 377, 447, 582, or 912 engine, you will find that our molded carburetor socket boots and manifold
flange boots will far outlast the original equipment or after-market parts now sold by others. We also make a socket
that will fit HKS engine flange mounted carburetors such as the Bing model 64.
JBM manufactures many sockets and boots to fit the popular Bing model 54 carburetor and special sockets to fit
older Rotax engines using the Mikuni type carburetors. Please see our Jabiru socket here.
JBM makes replacement Rotax "dual carb" intake silencer boots for Bing 54 that will last. If you are disappointed in
the amount of service you get from Rotax original parts, or don't like paying the high prices, please give the JBM
parts a try.... You cannot get a JBM original part from a Rotax dealer.
Another example is the Yamaha 650 motorcycle Mikuni BS-38, BS-34 , & BS34SS CV carburetor diaphragms
that were designed to be easy to replace, with limited production, and far less cost than buying original parts. We
now make over 14 sizes for older vintage motorcycles. Made in USA of high quality materials.

| Hi Don, Thank you for your speedy reply. Payment sent via PayPal. PS. I just returned from a 1,000 mile round trip after installing the new BS34 diaphragm set I borrowed from a good friend, and they performed excellently. I was very pleased. Ben Bennink |
| Just a quick note to say diaphrams arrived promptly and by following your website installation instructions fitted perfectly in a matter of minutes. Not yet fired the bike up yet as there are other things on list to do but I am sure it will run sweet as a nut!!. Again, your website is fab and while Kawasaki continue to charge £140 for each diaphragm (attached of course to a new slide which you don't really need), I can imagine you must be very busy. Keep up the good work. Regards, Nick. |
| Hi Don. I am sorry it took so long but I wanted to let you know that the diaphragms worked perfect for my bike and I have recommended you to a lot of people. Thanks again!!!!!!! |
| I received my diaphragm for my Keihin CV 32 carb for my KZ750/4 quickly and installed it with no problems. Following your instuctions on your website made it a piece of cake. It fit so perfect I can't believe guys are even considering the need for any type of glue. The bike runs the best it has run in years. Thanks for the great product and great service. Dave |
| Carb rubbers , wow , I must admit they are the best quality , I have a set on my plane which have done 4 years service and have never been touched , The plug caps and the throttle cable adjuster are just as good excellent quality , thanks for a great product , Regards Alex Rudd, ...South Africa |
| NOTE about new M-H-68 mm diaphragms to fit 28mm Mikuni Carbs: Received diaphragms and they fit perfectly. I still have a little work to do before a test ride but looking at how smooth the operation is I expect a vast improvement. Thanks for your help and producing a great product. Regards, Craig |
| JBM industries supplies copy carb sockets for the 447/503/582 and 912 engines. They also supply gaskets for the rotax engines and cable boots etc. Has anyone on the forum purchased their products, and if so what do they think of them. If you fit any of their products, is it a mod?? I fitted two of their carb sockets about 2 years ago to my Quantum 912 which I am half shares on. The reason we fitted JBM ones was because after trawling the net could find hundreds of hits about rotax ones failing. I couldnt find any on JBM ones failing. The fact that the JBM ones were a lot cheaper did swing it for us to try them out. Once they were delivered from America, took about a week, I must say I was impressed with the quality, they fitted spot on and there was a locking rib inside to locate the carb. Mine are still like new and I am happy, and would purchase them again. A friend of mine fitted some to his 582, and they are the same, still no signs of cracking, but only a year or so old. |

| Gidday Don I have already restored a 1980 XS650SG and a 1981 XV1000RH, and fitted your replacement Vacuum Slide diaphragms to both Makuni and Hitachi carbs. They work great with total reliability. I am now restoring a 1979 Yamaha XS750F which is an Australian production bike. The bike is all original and fitted with Mikuni BS34-11 carbs. I would like to purchase 3 replacement diaphragms to suit the BS34 CV carbs. |
| Thank you so much. The H-68 diaphragms worked great and fixed my Honda Shadow. The 20 dollars I spent on the diaphragms sure beat the 140 dollars quoted everywere else. Keep up the good work Oh, and by the way they worked/went on a 1983 Honda Shadow 500 with a dual keihin carb with metal slides thanks again, Chris |
| Hi mate my name is Lawrence borg i recently brought some diaphragms of u and they are brilliant better then the original by far i would also like an invoice for another 6 Keihin K'72,S diaphragms for My Honda VF 1000 F2 Its a 1985 model please. Laurie. Australia thanks mate. |
| The fitment of the Mikuni 70 mm diaphragm of the BS 34 SS CV works on the Mikuni BS 32 that is on my 1982 Kawasaki 650 H2 CSR also. Awesome fit and one of the easiest replacement parts I have ever dealt with. Just as you said it would on your website. james.hopkins1225@gmail.com |
