How to order JBM Industries rubber carburetor diaphragms, sockets, holders, boots, grommets,
springs, and parts for:
professionals that repair or service Rotax aircraft or vintage motorcycles.
  • First be SURE you measure and know exactly what you want. Don't guess! See if you can find the part listed on our site. See the
    "How to Measure" page for help in measuring diaphragms for motorcycles. Know what brand of carb you have! If you do not see
    the part listed, we don't make it.... We cannot answer questions about carburetors or what fits, as we simply manufacture parts.

  • JBM does NOT use factory part numbers.   Owner user groups or "lists" can tell you the JBM part that will work.
  • Send an email to to request a Pay Pal Invoice with your country and parts you want.
  • Be SURE to send it from the email address that you want the invoice returned to. Just describe the size measurement and
    part you want.... Original part numbers mean nothing to us, so please don't use them.
  • When you pay the invoice:  Be sure that you type your address correctly when giving it to Pay Pal. ...No need to email your full
    address to JBM. ( We get that from Pay Pal after you type it in. )
  •  Some find this all too difficult and complicated, and those folks should NOT order as you must be able to follow
    instructions exactly to install correctly........All we need is:
  •  #1: The country you are in. (to figure shipping.)
  •  #2: The part you want.
  •  #3: How many of them.

There is no "shopping cart"
JBM Industries does not know what carburetor or type of engine you have. We are a manufacturer and wholesaler of molded or machined parts. The
customer must know what parts he wants. JBM Industries makes no claims that the parts we manufacture will solve all your problems, or that you will know
how to install or use the parts we offer. Some parts require tools and knowledge that you may not have. If in doubt:
Have an expert order and install.
Any unused part we manufacture can be returned within 30 days if the buyer thinks it is not fit for use. The buyer is the final inspector.
Countries that JBM Industries
does NOT ship to; due to
unreliable, or slow mail delivery:

South America  ( all countries )
Do not telephone !
You must get our invoice first, then pay with any credit card.

PAY PAL clears all of our credit card sales.
WARNING: The person that pays, is the person we
must ship to. If you pay, we cannot ship it to your
brother, uncle, or service shop.  JBM cannot ship it
to a different country other than the one you have
listed with Pay Pal, so be SURE your address is
correct BEFORE you order an invoice from us.
Do not call on the telephone to order parts.
We have no method of taking your order.
MOST IMPORTANT: JBM DOES NOT CHANGE ADDRESS so be SURE your address is entered and correct with Pay Pal
How long does shipping take?  When will I get my parts?

These are questions that we cannot answer. Parts are
sent by the US Postal Service. Delivery is up to them and
we have no control over your delivery, and can do nothing
to "speed it up".
Foreign shipments are tracked until they leave the USA.
Then, there is no more tracking and the foreign country it
was sent to can help you find it. Please check with your
Customs Office about delivery or delay.

Questions to JBM about an order:
We strongly recommend you replace all
diaphragms at one time to preserve response
balance and prevent engine damage.
