ASSEMBLY STEPS
You'll need the following tools:
®Two 7/16" wrenches ( a 7/16" socket with a socket
extension and ratchet can be substituted for one of
the 7/16" wrenches).
• One medium size Phillips head screwdriver.
1. Unwind the throttle cable from around the en¬
gine. Do not kink or severely bend the cable.
2. Place the engine/transmission assembly so it
is resting on its "face" (the product name logo
label is face down).
3. Position the round end of the lower left han¬
dlebar in the slot on the left side of the transmis¬
sion - see Figure 3. (Look at the upper end of
the handlebar and check that the groove in the
half-round handlebar is facing inward. If not, in¬
stall the other lower handlebar in the slot.)
Figure 3: Attaching lower left handlebar.
4. Put a 1/4" flat washer (A, Figure 3) on the two
1/4"-20 x 5" long hex head screws (B) and insert
the screws through the handlebar and out
through the right side of the transmission.
5. Install the lower right handlebar over the ends
of the screws - see Figure 4.
Install a 1/4" flat
washer (C) and locknut (D) on each screw.
6. Slowly and evenly tighten the two screws and
locknuts. Snug the nuts down, but do not over¬
tighten them.
7. Place the upper handlebar between the top
ends of the lower handlebars (rubber handlebar
grips face to rear).

Align the hole in the left upper handlebar with
one of the two rectangular holes in the left lower
handlebar (the rectangular holes allow the han¬
dlebar to be adjusted higher or lower). From the
outside, insert a 5/16"-18 x 2" long curved head
carriage bolt (E, Figure 5) through the holes.
9. Put a 5/16" flat washer (F) on the bolt and
loosely thread on a handlebar knob (G). See
Figure 5.
10. Repeat steps 8 and 9 for the right side.
11. Tighten both handlebar knobs.

Phillips screw (H, Figure 6) down through the
hole in the engine ignition On/Off Switch bracket
(I).
Next, insert the screw through the hole in
front of the right side handlebar grip. Note that
the switch, wires and bracket are positioned to
the inside edge of the handlebar.
13. Install the rectangular rubber spacer (J,
Figure 6) on the screw and turn the spacer so
that its long end points toward the grip.
14. Align the hole in the engine throttle lever as¬
sembly (K) with the end of the screw.
