Earlier shift point
(looser screws)
• 2nd gear engages earlier
• Lower engine RPM and engine tone before 2nd gear engages
Later shift point
(tighter screws)
• 2nd gear engages later
• Higher engine RPM and engine tone before 2nd gear engages
ADJUSTING SHIFT POINT
Shift-point Screws – Initial Setting : Top of screw head fl ush with hole edge
Initially set the two spring-loaded shift-point screws so the top edges of the screw heads are fl ush
with the bottom edges of the holes. Both screws must be set equally.
You can adjust shift point with the two spring-loaded shift-point screws.
• LATER shifting: TIGHTEN both shift-point screws equally.
• EARLIER shifting: LOOSEN both shift-point screws equally.
IMPORTANT: Make equal adjustments on both shift point screws.
TRANSMISSION SHOE GAP
The 2-speed transmission shoes have gap-setting setscrews that allow you to adjust the gap between the shoes and the 2nd gear drum.
Always adjust the shoe gap to minimum, without the shoes touching the 2nd gear drum.
The shoe gap should be checked and adjusted periodically to compensate for wear.
ADJUSTING TRANSMISSION SHOE GAP
Transmission Shoe Gap – Default Setting: 1/2 turn loose (from tight)
When building the 2-speed shoe assembly, set the gap so that the two shoes are
equal distance from the 2nd gear drum.
1. Assemble the 2nd gear shoe assembly, and set both gap-setting setscrews
equally so that each one just lightly touches the central adaptor. The
setscrews MUST NOT protrude beyond the shoes.
2. Install the drive pin in the layshaft.
3. Slide the 2nd gear shoe assembly onto layshaft and seat it over the pin.
4. Slide the 2nd gear onto the layshaft; the drum goes over the 2nd gear shoes.
There should be equal but minimal spacing between the 2-speed shoes and
the inside of the 2nd gear drum.
5. Rotate the 2nd gear until you can see a gap-setting setscrew through the
hole in the drum.
6. Insert a hex key through the hole and into the setscrew.
7. Tighten the gap-setting setscrew until the 2-speed shoe just touches the
inside of the alu. 2nd gear drum.
8. Loosen the setscrew by ½ turn (CCW).
9. Repeat steps 5–8 for the other shoe; be careful not to adjust the same shoe
twice.
10. Spin the 2nd gear; it should spin freely without binding or dragging.
11. Install the 1st gear.
Adjust the gap by loosening or tightening both setscrews equally:
• LARGER gap (shoes further from drum): LOOSEN both setscrews equally.
• SMALLER gap (shoes closer to drum): TIGHTEN both setscrews equally.
IMPORTANT: Make equal adjustments on both gap-setting setscrews.
Setscrews must
NOT protrude
Top of screw head
should be level
with hole bottom
edge
Do not overtighten gap-setting
setscrews. Only tighten until roller
pins contact the center hub.
TO SHIFT LATER
Tighten both screws equally
TO SHIFT EARLIER
Loosen both screws equally
TO INCREASE SHOE GAP
Loosen both screws equally
TO DECREASE SHOE GAP
Tighten both screws equally
