What should I do if my motorcycle runs with the choke on?
Start your motorcycle and keep pouring about 1/4 to 1/3 can of Sea Foam into the funnel while it runs. Note: you’ll see a lot of white smoke coming from your exhaust. That’s normal. When your engine burns all the Sea Foam, it will stop. Reattach the fuel line to the tank and let your bike sit for 10 to 15 minutes.
Why does an engine only run on choke?
An internal combustion engine needs a precise mixture of fuel and air to run properly. When the engine is cold, it needs slightly more fuel in the fuel/air mixture for it to start, which is what the choke does. The choke increases the amount of fuel in the mixture, creating a richer mixture.
Why does my air conditioner turn off when I Turn Off the choke?
It can be caused by an air leak. Air leaks can be caused by cracks in the vacuum lines on some carbs, a crack in the air boot, or simply a loose clamp between the carb and the air boot. Remember, more air in the system means a leaner air/fuel ratio, thus causing an overly lean condition when the choke is turned off.
How do you put a choke on a bike?
In case you do not know how to use a choke, simply pull the level to ‘ON’ and start the bike. The bike might start off with high revs or start easy and then move to high revs. Keep the choke in ‘ON’ until the engine is sufficiently heated and then switch it back to ‘OFF’.
Why does my dirt bike only run on choke?
You won’t see one of these on a dirt bike because the choke circuit actually just adds more fuel to the mixture with the same amount of airflow. So, a far too lean air/fuel mixture is why your bike only runs with the choke on.
What happens when you turn the choke on for a carburetor?
When you turn the choke on for a carburetor, it is creating a rich condition. This makes the bike easier to start, by increasing the amount of fuel present in the air/fuel mixture. When an engine is cold, it needs a little richer mixture in order to get up to operating temperature.
Can a new bike start without a kick start?
The sad part about this is majority new bikes are launched without a kick start option. As much as I appreciate the thought to reduce rider effort to get the bike started, I loathe the part where the rider cannot get his machine started when the battery juices are not up for it.
What should I put in my gas tank for my motorcycle?
Fill your tank with the recommended grade fuel for your motorcycle. Add to the tank one ounce of Sea Foam for every gallon of gas in your tank. Ride your motorcycle and allow the additive to work its way through. If this doesn’t work, go to the next step.
Do you need to tune the fuel mixture on a motorcycle?
Once you have the motorcycle up and running, you will need to tune the idle mixture. Every carburetor is equipped with an AIR or FUEL screw to tune the air fuel mixture at idle.
What happens when you tap the choke on a bike?
New tank, new fuel system and carbs have been cleaned and rebuilt recently with stock internals. No upgrades just bone stock carbs. New battery, replaced round fuses with contemporary plug in fuses. Bike finally runs on the choke but runs like crap. Rough on idle, when I tap the throttle bike dies.
What causes a motorcycle engine to only run on choke?
Tiny debris particles from dirty fuel can easily block a jet, but the most common cause of clogged jets is stale fuel sitting in the carb when the bike or ATV is inactive. When fuel breaks down, it leaves behind a gummy residue, almost like a varnish that builds up on everything it touches, including the pilot and main jets.
When do I tap the throttle bike dies?
Rough on idle, when I tap the throttle bike dies. When I take off the choke bike dies. If I leave the choke on and let the bike get warm it runs for a bit and then slowly dies. When trying to ride it hesitates and then jumps to life and then hesitates, sounds like left side backfires. Sounds like its not getting The proper spark.
How long does it take for a choke to come off?
Within the first 20 or 30 seconds the choke should come off and the required fuel/air mixture is then supplied by the pilot circuit. Your pilot circuit is obviously not doing its job. Everyone always says they have cleaned the carbs, but many really don’t understand how the carbs work, or what to look for.
