Tips
Upon receiving your vehicle (and after reviewing the video) we recommend that you heed
the following tips:
1. Perform your first oil change by replacing the Engine oil with 10W40 motor oil prior to
starting. Always remember to check the oil level on your dipstick after adding new oil to see
if the oil is at the right level. It is better to use fresh unleaded gasoline. If your vehicle has
been unused for an extended period of time, remember to replace the gasoline before use.
2. Always remember to check and tighten your bolts before you ride for safety. You can also
use a little Loctite Threadlocker to reinforce the loose screw.
3. Make sure kill switch on left handle bar is OFF. If the kill switch is engaged, the unit will not
start.
4. Make sure the fuel valve is in the ON position. If it is in the OFF position, there will be no
gas flow and the unit will not start.
5. Make sure the choke on the carburetor is in the UP position when you try to start this bike.
Turn the choke off after the engine gets warmed up enough.
6. When you want to shift gear, you need to hold the clutch lever and DO NOT twist the
throttle grip to accelerate. The gear setting is N-1-2-3-4, move the gearshift up to upshift
and down to downshift. You will need to have some skill to properly gear shift, this may
take practicing several times.
7. Always make sure the front and rear chain sprockets are on a straight line. And then adjust
your chain to proper tension if necessary.
8. Lightly step on the starter lever a few times to make the engine rotate. After feeling the
compression resistance, release and return the foot starter lever back to the highest point,
then step on it hard and fast. Use the maximum force on the last stroke of the starter lever.
If you have any questions or issues, just feel free to contact us, we are always here to help.
Thank you!
