From time to time, you might encounter some issues with your pitbike. Don’t panic, ATOMIK experts have compiled the following list to help you identify the issue and fix it with minimal fuss.  If the particular problem you are having is not listed here, please feel free to contact our service centre.

1 - Soft brakes

a. When you’re brakes are soft, it can mean several things.

 • You have a leak in one of your lines

1. Clean your lines
2. Check and see if there are any leaks when you push on your brakes.
3. If there is, then that’s your problem, if not, then

You most likely have air in your lines or not enough fluid

1. Air in your lines or not enough fluid makes it almost impossible to generate hydraulic pressure so your brakes will feel very soft.
2. Check to see fluid levels are low or not. If low, then add more fluid.
3. Grab a wrench and loosen the bleed bolt on your brakes just a tiny bit
4. Push down on your brakes until to start to feel some pressure and then hold on.
5. Now loosen the bleed bolt and let the pressure take the air out before quickly tightening the bleed bolt again.
6. Pump your brakes and hopefully you will have pressure. This whole process is called “bleeding your brakes”
7. If it doesn’t work the first time, then try three or four more times. If it still doesn’t work, then

Your brakes are out,

1. You need to replace them

2. Got no Spark?

Check the spark plug

1. Pull out your spark plug and give it gentle scrub with a wire brush or sand paper.
2. Also, if the spark plug is wet, dry it
3. Put the spark plug back in the ignition coil 
4. Place the tip of the spark plug on something metal
5. Make sure everything is plugged in and that nothing is loose
6. Kick the bike over and see if you see a spark.
7. If you see a spark, then you’re back in business
8. If not, then try again using a new spark plug.

If it still doesn’t spark, then it may be your killswitch

1. Locate your killswitch and unplug it.
2. Try to kick the bike over again
3. If you get a spark, 

a. Then put the spark plug back into your bike while leaving your ignition coil cap on. 
b. Leave the killswitch unplugged and kick your bike over again.
c. It should run. Pull the ignition coil cap off the end of the spark plug to kill your bike
d. Go and get a new killswitch

If you don’t get a spark,

1. Then we have narrowed it down to three things, CDI, Ignition Coil or the Stator Assembly

a. Check the Stator

i. Easiest way to know if your stator is dead is by smell. If it smells burnt, then its gone. 
ii. To check it, just use a multimeter and check the reading. If resistance is approximately 100 ohms, then the Stator is fine. If it is more or less, then it is on its way out. If it gives you nothing, then its dead.

b. If you’ve got a mate who has a similar bike which is working, then ask if you could test the CDI or Ignition Coil on it. If you don’t, then just bring it to your nearest service centre and get them tested. 

By now, we hope you’ve managed to get your bike started. If it hasn’t, then you either have a problem with your engine or carburetor.

3. Got spark but the bike won’t run?

a. Then the most likely solution is to tune your carburetor because your bike is mostly likely running rich or lean

Remove your spark plug and have a good look at the colour of the tip. If the color is;

1. White/whitish – Then 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 to lean or rich, just right)

Have a look at the manual that came with your bike and it should have instructions on how to adjust the carburetor. It is usually a matter of turning the mixture screw either clockwise or anti clockwise to make the mixture leaner or richer. You wouldn’t want to turn the screw anymore than one half turn at a time.

To test whether your bike is still running rich or lean, just;

1. Make sure your spark plug is clean
2. Take your bike for a 5 to 10 minute spin, HARD!
3. Take the spark plug out and see what color it is.

The other problem you might causing your bike to run rich or lean is that your carburetor needle might be too high or low. If the bike is running rich, then you might want to lower the needle one notch and visa versa if it is running too lean

4. Other common issues

a. Bent fuel line?

Usually it’s because your hose is too short. Just get a longer one.

b. Choked up?

You’ll know if you’ve left your choke on if your bike starts to splutter or stall when you add throttle. If you’re new to riding bikes, just remember to only have the choke on when you warm up and off when you ride. Simple as that.

c. Feeling jumpy?

Just make sure to check and clean your air filter regularly because if not, you sometimes get dirt in your carburetor and your bike will jump a bit when you ride. 

d. Bit wet out there?

Just remember that after every time you ride in the wet, your ignition coil may have gotten wet as well. Just so you have no worries starting it up the next time you ride, just make sure to dry out your ignition coil after each ride in the wet. 

e. Retire your fuel

Just like us, fuel gets old. So if you haven’t taken your bike out for a few months, make sure to change the fuel by draining it and sticking new fuel in.
