MAINTENANCE PROCEDURES
CLUTCH LUBRICATION
The life span of your drive chain will depend upon how well you take care of
it. Proper drive chain maintenence will also extend the life of other parts on
your MBx10, like the drive sprockets and the clutch.
IT IS CRITICAL THAT YOU CHECK THE DRIVE CHAIN
TENSION AND LUBRICATE IT EACH TIME YOU RIDE.
Excessive play in the drive chain can
result in the chain coming o and
damaging the engine cases, or excessive
clutch noise. A chain that is too tight
can cause excessive wear on drive train
components and lead to premature
failure. To check and adjust the chain
to the proper tension, follow these steps.
With the engine turned o, check the slack in the lower part of the chain by
pushing upward on it with your nger. The vertical movement should be
between 3/8” and 1/2”. To adjust the tension of your drive chain, see below.
Always inspect your drive chain to be sure it is well lubricated and in good
condition. Watch for damaged rollers or pins, dry or rusted links or any kink-
ing of the chain.
If you are not able to adjust the tensioner enough to get proper tension on
your drive chain, you need to replace your chain.
Your MBx10 mini bike uses a centrifugal clutch
which requires periodic maintenance to operate
properly. If you experience a noisy or “grabby”
clutch, especially if it kills the engine at idle or
low speeds, it is time to service your clutch.
To do so, follow these steps:
1. Remove the chain tensioner wheel.
2. Remove the chain guard.
3. Remove the chain from the drive sprocket.
4. Remove the clutch retaining bolt in the
center of the clutch and slide the clutch
assembly o of the shaft.
5. Using a pair of snap ring pliers, remove the
snap ring that is located around the sprocket.
6. Pull the assembly apart and wipe it down,
inside and out with a clean cloth.
7. Then locate the thin shim around the shaft
and remove it. Set it aside.
8. Using a high quality, high-temperature wheel
bearing grease, coat the clutch shaft with a
good layer of lube.
9. Replace the shim and re-assemble the clutch.
10. Place the clutch mechanism back on to the
drive shaft.
11. Replace the bolt in the end of the shaft that
holds the clutch in place with a new 6mm x 20
or 1/4”-28x3/4” socket head cap screw and
hand tighten.
12. Tighten the retaining bolt to 90 -120 in. lbs.
