Step 7: Insert & thread the 5/16-18
bolts with their washers through the
top holes of the backing plate &
tighten. Do not over torque. Use blue
threadlocker (med strength). Always
check that the 5/16-18 bolts have a
hole drilled through them. This
allows the motor to breathe.
Step 8: At this time tighten both hose
clamps on coupler & tighten
enrichener knob nut to the backing
plate. Make sure carb & coupler are
correctly & fully seated.
Step 9: Install the air filter onto the
backing plate. Flat side goes in
towards backing plate. Contoured
side faces out towards Air filter cover.
Step 10: Install Air filter cover with
the 1/4-20 countersunk head bolts.
Use blue threadlocker (medium
strength)
Between the Steps 1 & 2 you will need to mount the 140 adapter
to the rear cylinder. Make sure the 5/16-18 bolt that goes through
the adapter into the breather/spacer has a hole drilled through it
to allow the head to breath into the atmosphere. The secondary
hole (w/integrated nut) in the adapter will allow for you to
mount the backing plate as described in Step 7. It is important
that the 5/16-18 bolts that are fastened to the head have the hole
drilled through them. This will allow the motor to breath
properly.
130 & 140 EL BRUTO
NOTE: Due to the cylinder height & spread of the 130 & 140 El Bruto motors, an adapter is required
& provided to properly mount the Ultima air cleaner assembly.
