The Choke Demystified: Your Cold Start Companion
Modern, fuel-injected bikes have largely made the choke a thing of the past. But on carburetor motorcycles like the beloved Honda XR150L, it’s a vital tool for a smooth start, especially when the engine is cold.
What is the choke?
Simply put, the choke restricts the amount of air entering the engine, creating a richer fuel-to-air mixture. This richer mixture is easier for a cold engine to ignite, helping it fire up reliably.
When to use it?
You’ll primarily use the choke for cold starts. Think first thing in the morning, after the bike has been sitting for a few hours, or on a cooler day. In the hot Vietnamese climate, you might find you need less choke, or even none at all, if the bike has just been ridden, or if the ambient temperature is high and it usually is.
How to Use it
Here are the steps you need to take to use the Choke correctly:
Locate the Choke Lever
On most XR150s, it’s deep in the engine space and a little tricky to find. You’ll typically find three positions:
– Fully Down (Off): Your normal riding position.
– Middle (Half Choke): For slightly cool starts.
– Fully Up (Full Choke): For genuinely cold mornings or overnight starts. Image Suggestion: A sequence of three photos: choke fully down, half up, and fully up.
Assess the Coldness
Decide between half or full choke. For a truly cold engine, go for full.
Ignition ON
Turn your key to the ‘On’ position.
Find Neutral
Get your bike into neutral (the green ‘N’ light on your dash should illuminate). You can double check by rocking the bike back and forth.
Start the Engine
Press the starter button. Crucially, do NOT touch the throttle. The choke is doing its job of providing the rich mixture; adding throttle will only flood the engine, which means too much fuel for combustion.
When To Take The Choke Off
This is vital! Running with the choke on for too long can damage your engine, foul your spark plug, and waste fuel. It is also extremely dangerous because you will find the engine lacks response and acceleration when the fuel mixture is so high.
As soon as the engine starts and settles into a higher idle, begin to gradually push the choke lever down. Listen for the engine to smooth out and the RPMs to drop. If it sputters, push the choke back up slightly, wait a bit longer, then try again. Once it idles smoothly without the choke, you’re good to ride!
Common Choke Mistakes to Avoid for New Riders
Forgetting to turn it off: If your bike feels sluggish, is blowing black smoke, or smells rich, check your choke!
Over-revving with choke on: Let the choke do its work at a steady idle.
Using it when the engine is warm: You generally only need it for cold starts.
Applying throttle during starting: This can flood the engine, making it harder to start.

FAQ
Why do I need to use a choke on my Honda XR150L? Don't modern bikes start easily?
Unlike many modern bikes which are fuel-injected and automatically adjust the fuel-air mixture, the Honda XR150L uses a carburetor. The choke manually enriches the fuel mixture by reducing the air intake, making it much easier for a cold engine to start and run smoothly, especially in the mornings or after being parked for a while.
I'm concerned about breakdowns during my motorcycle touring Vietnam trip. What kind of support can I expect?
Rentabike Vietnam offers roadside assistance wherever possible. We do this by having a dedicated phone number on your key ring to call, guidance for local mechanics, or even bike swaps in major cities. We do our best to make sure you have a great motorcycle touring Vietnam adventure.
Is the Honda XR150L a good choice for a new rider exploring Vietnam?
Absolutely! The Honda XR150L is an excellent choice for new riders in Vietnam. It’s relatively lightweight, forgiving, and has a comfortable upright riding position. Its 150cc engine is powerful enough for Vietnam’s roads, including mountain passes, but not overwhelming for beginners. Its reliability also makes it a popular choice for motorcycle touring Vietnam.
Can I just leave the choke on while I'm riding? What happens if I forget to turn it off?
No, you should never ride with the choke fully on for an extended period. Leaving the choke on too long will cause your engine to run “rich” (too much fuel), leading to poor fuel economy, black smoke from the exhaust, fouled spark plugs, and potentially long-term engine damage. It can also be sluggish when riding and that can be very dangerous in fast traffic. Always push the choke lever off once the engine has warmed up and is idling smoothly.
My bike started with the choke on, but now it feels sluggish and is blowing black smoke. What's wrong?
This is a classic sign that you’ve likely forgotten to turn the choke off after your engine warmed up. Simply push the choke lever all the way down to the “off” position. Give the engine a minute or two to clear itself out, and it should return to normal operation.
Ready for Your Vietnam Motorbike Adventure?
The Honda XR150L is an incredible machine for exploring Vietnam. Mastering simple techniques like using the choke will make your riding experience smoother and more enjoyable, especially if you’re embarking on your first motorcycle touring Vietnam trip.
