clamps on each end of carburetor.
5. Adjust pull cable until wide-open
throttle is achieved. Adjust return
cable to take up the slack (for twist
throttle only). Note: When throttle
cables are adjusted properly,
there should be approx. 1/8" of
free play in the throttle.
6. After throttle cables have been
adjusted the handle bars should be
rotated from full right stop to full left
stop while opening and closing
throttle to ensure smooth
operation. Also check to make
sure the cables do not catch or
bind on anything, i.e., hand
guards, stabilizers.
7. Connect crank vent line to the
plastic elbow on upper left side of
the plenum.
8. Install remote idle cable into
threaded tab on top of carburetor.
Refer to main instruction for remote
idle cable installation and
9. Install fuel tank and connect fuel
line to petcock and secure with
remaining pinch clamp. Turn fuel
on and check for leaks.
10. Open throttle 3-5 times to prime
accelerator pump. Do not open
throttle any more than 5 times as
this may flood engine!!
11. Install air box bolts back into frame
to secure air box.
NOTE: If flooding occurs, slowly
open throttle about half way and
hold. With throttle still open,
engage starter until engine fires
