• Yamaha SX 650 & TX750 Carburetor Holder Socket Rubber Flange Intake Boots are made to run in all commonly
    available fuels, including those with alcohol. These parts are manufactured from high quality TSR compound and
    are designed to operate without metal covers or cans, yet will still support the carburetors. They will not give
    rapid age cracking or swelling. These rubber flanges use a steel insert plate, and are designed to run using a
    automotive type hose clamp. JBM can supply a nice 1/2" wide stainless clamp for $3.80 each.  ( NOTE: Tighten
    clamps only until carb will not move in the rubber! ) See below for "straight type" used on early 650 and TX750.

for your Mikuni BS38 & BS34CV carburetors.
Straight flanges were used on early 1970 thru 1973 engines and
use a BS38CV Carburetor. These also fit Yamaha TX 750 engines.
$64 pair
BS34mm Used from 1980 on. Also use on some "VM" carbs
BS38mm with angle used from 1974 thru 1979
Early model Yamaha 650 twin engines used a flange
without angles on it and a BS38CV carburetor. Fits TX 750,
too. Face

    These holders use Clamps only !
Most frequent question we get is: Will they hold the
carburetors and air filters unsupported?
Answer: Yes as that is how it is done on the aircraft engines.
Some folks even hang an unsupported silencer box on them, but
we do not recommend that much weight. See ultralight photos.
JBM Industries makes BS38CV
holders without angle for early
models 1970-1973
Straight version for early models
shown at bottom
of page.
Vacuum tubes are
NOT
recommended as
they weaken the
plate.
Work for 36mm/38mm VM/TM not the 30mm to 34mm VM carbs.
Notes:  JBM Yamaha 650 carburetor holders that are angled have rubber covered metal plates. Gaskets
may not be needed.
 
JBM Yamaha 650 carburetor holders that are straight do NOT have rubber covering the metal plate, so
gaskets MUST be used.
 Be sure your bolts have at least 5 full turns of engagement into the cylinder head. Use Loc-Tite on the
threads, and don't over tighten as the metal plate can be bent.
 Do not over tighten hose clamps, as they can cut into the rubber.
JBM no longer drills the plates or installs vacuum barbs, as this weakens the plate and takes too much time
for us to do. Customer must install his own barbs at his own risk.
Due to production demands, these holders will be marked sold-out from time to time, so if you need them,
buy when available!
