REPAIR AND MAINTENANCE
❑ Chain and Sprocket Adjustment – Mini Chopper
Note: Late model Mini Electric Choppers and Rebellion Electric Choppers are equipped with a chain tensioner, are self
adjusting and will not use this method to adjust the chain.
The chain will typically have a “loose spot” and “tight spot” corresponding with a particular sprocket rotational
position. This is normal and common to all chain-driven vehicles due to run-out tolerances of freewheel and sprocket.
The chain should be adjusted to the ideal tension with chain in the tightest spot.
Proper chain alignment must be maintained.
The wheel must not be skewed. If the chain is noisy or rough running, check the lubrication, tension and alignment of
the sprockets, in that order.
If the wheel is skewed, follow steps on page 6 to align the wheel and adjust the chain.
1 Use the special valve extender/
adapter supplied. This item is
concealed in the grip on the speed
control side of the handlebar.
2 Align the access hole in the
drive sprocket with the tire valve.
Thread the adapter completely onto
the valve and attach the pump.
Inflate to the PSI indicated on the
tire sidewall.
3 Remove valve adapter immedi-
ately after inflating.
❑ Inflating the Tires
Tires are inflated when shipped, but they invariably lose some pressure between the point of manufacturing and
your purchase.

4 Place the adapter back into the
handlebar grip for later use.
1 Using a bicycle style tire pump
equipped for a Schrader-type valve,
inflate the front tire to the PSI indi
-
cated on the sidewall of the tire.

WARNING:
Failure to
remove the valve adapter after
inflating will cause the inner tube
and/or adapter to be severed by the
rear drive sprocket.
Note: If you lose the adapter,
a valve stem extender can be
purchased at almost any auto parts
store.
Note: The pressurized air supplies
found at gasoline stations are
designed to inflate high-volume
automobile tires. If you decide to
use such an air supply to inflate
your electric chopper tires, first
make sure the pressure gauge is
working, then use very short bursts
to inflate to the correct PSI. If
you inadvertently over-inflate the
tire, release the excess pressure
immediately.
