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
|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.
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
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??
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.

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. firstname.lastname@example.org
|I would like to thank you for the excellent service, the diaphragms arrived here in the U.K. nine days after I made payment.. Fitting the diaphragms on my twin
BS34 carbs was a breeze and the complete job took me around 10 minutes thanks to a well designed, good quality product and the clear instructions on your
website. Well done JBM Industries. Regards, Martin Baldwin
I got home seen the K-72-S diaphrams were here for my Honda VT700c, installed and the bike runs great!!!!!!!!!!!!!!!!! Thanks, Rob.

|Don -I finally got around to installing the diaphragms last night. Very happy with them. The fit was perfect and now the slide action is silky smooth...great
product and beats the hell out of spending big $$ on new slides. Jack Turner
|The 70 MM diaphragm I ordered works great in my Mikuni Carb, although it wasn’t designed for this model! (2000 Arctic Cat 4X4 ATV 300cc) Your product is
far less expensive than OEM at $139. Please let me know if you decide not to carry or produce the 70mm diaphragm as I will need to order a few spares.
Thanks again for a great product and fast shipping. ....Ben Stacy
