DRIVE CHAIN MAINTENANCE
ADJUSTING THE IDLE SPEED
The idle speed is the RPMs of the engine when it is at idle, or not being
accelerated. If the idle speed is too low the engine is running to slowly and
can die when you are stopped. If the idle speed is too high the scooter won’t
stay still when idling and may try to move forward.
To adjust the idle speed, locate the
idle speed set screw that is behind
the air filter housing on top of the
carburetor. Using a flat or phillips
screwdriver and with the engine
running, turn the screw in (clockwise)
to raise the idle speed and out
(counter-clockwise) to lower the idle
speed.
Be sure to have a friend hold the scooter brakes while you adjust
the idle speed so it doesn’t move forward unexpectedly.
The fuel tank on the MVs10 must be kept clean to keep the engine running
smoothly and efficiently. Over time, sediment can build up in the tank and
get caught in the inner workings of the carburetor causing clogs and poor
performance. To help avoid contamination and sediment build-up be sure
to always wipe off the area around the fuel cap before you open it, as well as
the spout of your fuel container
before pouring in fuel.
Locate and remove the two tank
mounting bolts behind the fuel tank.
Leaving the hoses connected, remove
the cap and pour out the contents.
Add some clean fuel, replace the cap
and swish it around a little. Then
remove the cap and pour it out.
Replace the tank to its mount and
re-fill the tank with clean, mixed fuel.
The drive chain needs periodic maintenance to protect it from premature
wear and from coming off while riding if it becomes too loose. The drive
chain should have a little bit of slack in it, approximately 1/4” movement in
either direction or about 1/2” total movement.
With the engine off, locate the drive
chain behind the chain guard on the
right side of the scooter. Press on it
from the top to see how much slack
is in the chain. If it has more than
1/2” of movement then your chain is
probably too loose.
To adjust the tension of the chain,
loosen the rear axle nut on both sides
of the wheel. Then, using a 10mm
open end wrench, screw the adjuster
nut in (clockwise) a few turns. Be sure
to adjust the same amount on both
adjuster nuts to keep the rear wheel
straight. Check the tension on the
chain again and repeat as necessary
until the chain feels right, then tighten
the axle nuts on both sides to hold it
in place.
To lubricate the chain, raise the rear
of the scooter up onto a block or
platform so that the rear wheel spins
freely. Then using one hand, spin the
rear wheel while spraying lube onto
the drive chain. Any standard lube
will work, but do not use a lube with
a degreaser in it, like WD40 because
it tends to dissolve the lube that is
inside the rollers, shortening the life
of your drive chain.
