JBM Industries in Kent, Ohio makes many machined and rubber molded parts of high quality. The parts offered
here are manufactured by us right here in Kent.
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, too. Vibration Isolators and Stainless Steel Exhaust Springs that fit a wide
range of 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.
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.
JBM Industries can make custom molded parts, or run your tooling to make parts for you.
JBM Industries solves problems. An example is the Brunswick A2 bowling ball return bumper guides used to
replace older cracked original parts. JBM designed a solution for cheap after-market solutions to this problem, that
just don't hold up. JBM built the tooling and is able to run the extremely low volume production this job requires.
Another example is the Yamaha 650 motorcycle Mikuni BS-38 CV carburetor diaphragms that were designed
to be easy to replace, with limited production, and far less cost than buying original parts. Design and tooling all by
JBM Industries and made in USA of high quality materials
Yamaha 650 twin carburetor holder rubber intake manifolds is one of our latest projects. Made of high quality
TSR compound, these parts are made to replace the very inferior imported parts now being sold for these vintage
motorcycles. Click on picture for more information.
