The clutch on your MBx10 or MGk10 could be in need of some lubrication. Refer to the maintenance videos section of the type of unit you own for How To information, or contact your local Motovox Service Center for help. Go to the Locate a Dealer section under Action on the home page of this site or call 888-488-6686 for help.

The type of oil you should use varies by type of engine. Here is a list of oils to use by model name:
MBx10/11/12 – A high-quality 10w30 motor oil
MGk11/12 – A high-quality 10w30 motor oil
MVs10 – This uses a two-stroke oil mixed with the gas to lubricate the engine. Use a high-quality 40:1 ratio 2-stroke oil in your fuel mix.
MVx70 – This has a wet clutch, so it’s best to use a 30 weight non-detergent motor oil.
MBx10/11/12 – 135 Lbs.
MVs10 – 165 Lbs.
MVx70 – 165 Lbs.
Note: The performance of your Motovox vehicle will be substantially reduced with heavier drivers.
We have noticed that a few of the fuel caps on the MBx10 have been leaking fuel while operating. The simple fix is to remove the rubber seal inside the cap and locate the foam block inside. The size of that foam block should not be larger than a sugar cube (about 5 centimeters square). You can cut the size of the foam block down with a pair of scissors and re-assemble the cap, which should alleviate the leaking problem. If not, call our Service Department at 888-488-6686 for help.
Check to make sure that the choke lever is in the OFF or RUN position. For help locating the choke lever for your model, refer to your Owners Manual or contact our Service Department at 888-488-6686 for help.
- Be sure of all the following:
- Is there fuel in the tank?
- Is the kill switch in the ON position?
- If your Motovox is equipped with a key, is it in the ON position?
- If your Motovox is equipped with a fuel shutoff valve, is it in the RUN or OPEN position?
- Remove the spark plug and see if it is in good working condition. To do so, refer to your owners manual or find the Spark Plug video in the Maintenance Videos section of your model on this website. Or contact us at 888-488-6686 for help.
- Check to be sure that your fuel line is not clogged. To do so, refer to your owners manual or find the Fuel Line video in the Maintenance Videos section of your model on this website. Or contact us at 888-488-6686 for help.
Maintaining the engine oil is the single most important thing you can do to keep your Motovox running a good long time. We put oil in the crankcase of each one at the factory when we test start them, but you don't want to count on the oil being at the proper level or in perfect condition. Metal shavings or "slag" can remain inside your crankcase from when it was built and cause problems down the line. It is strongly recommended that you change your oil after the first 2 hours of operation and replace it with a good quality 10w30 motor oil (excludes the MVs10 stand up scooter which does not have crankcase oil).
The correct fuel mixture for the MVs10 is 40:1. We apologize for the error in the owners manual. Use a good quality 2-stroke oil and mix thoroughly in a clean container before pouring into the MVs10 fuel tank. Be sure to completely empty the container before mixing a new batch so that the mix doesn't become too rich after several mixes.
It is most likely that the carburetor float is stuck in the open position. To fix this problem, locate the carburetor float bowl behind the engine - it is the gold-colored round bowl-shaped object between the air-breather and the engine, on the bottom of the carburetor. With the fuel shut-off valve in the OFF position, use a screwdriver handle to tap the float bowl three or four times. This should dislodge the stuck float. Turn on the fuel and see if the leak stops. If not, contact Motovox at 888-488-6686 for help.
