ASSEMBLY 11.

BRAKE ISSUE
Clean brake lines via compressed air if not resolved see below points.(Possibility air or not enough uid in lines)
- Air in your lines or not enough uid makes it almost impossible to generate hydraulic pressure so your brakes feel very soft.
- Check to see uid levers are low or not. If low, then add more uid.
- Grab a wrench and loosen the bleed bolt on your brakes just a tiny bit.
- Push down on your brakes until to start to feel some pressure and then hold on.
- Now loosen the bleed bolt and let the pressure take the air out before quickly tightening the bleed bolt again.
- Pump your brakes and hopefully you will have pressure. This whole process is called“bleeding your brakes”
If this doesn’t work the rst time, try again up to 4 times, if still no result your brakes make be out and need replacement
GOT NO SPARK
- Check spark plug for oil or residue, if found clean and dry and t plug
- Connect spark plug to coil and place on something metal. if spark plug is working this will create a spark. If no spark please try new
spark plug
If the replacement spark plug does not work, please see below points to eliminate the issue.
- Locate kill switch (front and rear), than remove kill switch and if sparks you have located issue, if not please see next point
CHECK STATOR
The rst indication that you have a dead stator or magento can be from a burnt smell or you can check with a multimeter. If resistance is
approximately 100 omhs, then the stator is ne. If it is more or less, then its on its way out. If it gives you nothing its dead.
If you have a mate who has a similar bike which is working, than ask if you could test the CDI or ignition coil on it. If you don’t, then take the item
to your local small engine mechanic to get them tested.
Please check all the wiring housing and cup lings are connected.
If none of the above resolves the issue, this is an indication that the product needs to be assessed by a small engine mechanic.
TROUBLE SHOOTING 12.

GOT SPARK BUT BIKE WON’T RUN
Common issue for this is your bike is running rich or lean
Remove spark plug and have a good look at the colour of the tip, if the colour is;
1. white/whitish –than you’re running lean (not enough fuel)
2. Black/Blackish –Then you’re running rich (too much fuel)
3. Brown – Should indicate a healthy carburetor (not too lean or rich, just right)
-make sure that the carby manifold is tightened correctly with no air or gaps, if so please tighten.
-try spraying aero start in the air lter, than try starting the bike. If this starts the issue is resolved, if dies out please see below.
TEST IF BIKE IS RUNNING RICH OR LEAN.
1. Make sure your spark plug is clean
2. Take your bike for a 5 to 10 minute hard spin
3. Take the spark plug out and see what colour it is.
The carburetor needle could be too high or low, which could cause the bike to run rich or lean. If the bike is running rich, than you might want to
lower the needle one notch and visa versa if it’s running too lean.
OTHER COMMON ISSUES
- Retire old fuel
- Fuel does get old, it is recommended to drain fuel and replace with fresh fuel as fuel life expectancy is 1 month for 4 stroke.
- Knicked fuel line
- Fuel line knicked is due to the line being to short, replace with longer fuel line
CHOKE IN UPRIGHT POSITION
- If product is spluttered or stall this is generally because choke is in the upright position. Please only keep choke in the up position
when warming up and then place down while riding.
CUTTING IN AND OUT
- Please remove air lter and give a good clean and place back in.
BIKE EXCESSIVELY WET?
-Ensure after each ride that the product is dried around all electrical components.
(Hint) Water replacement (DW40) spray on cup lings can help remove water)
