Why does my bike not start when I give it throttle?

Why does my bike not start when I give it throttle?

Check the carb diaphrams. If there is a slit of hole in the diaphram (s) the needle will not lift (giving it more fuel) when you roll on the throttle. Hold the diaphram up to a very bright light and look carefully. Also, if the air passages running up to the diaphram chamber are blocked, the slide will not lift.

What to do if your engine dies when you open the throttle?

If its a 2 stroke then spark plugs are expendable items, change it even if its a 4 stroke. If it doesn’t sort the problem then at least it wont do any harm! Failing that then it sounds like you either have an air leak or a fuel problem. First things first, start the engine up then spray copious amounts of WD40 around the inlet manifold.

What’s the idle speed on a Yamaha bike?

The bike hasn’t been running to my knowledge for 4-5 months. Prior to my purchase the previous owner, a friend, said he cleaned the carbs. Basically, she’ll start up fine and idle around 1500-2000 rpm (full choke) but upon going to 1/2 choke or giving her any throttle, she dies.

Where is the slow speed jet on a bike?

Remove the float bowl and the slow speed jet is located next to the main jet, remove it and look thru the center you want to be able to look thru it (like a baby telescope) and see thru it cleanly and clearly. You can refer to a shop manual, parts manual, or possibly owners manual.

Why does my Kawasaki die when I throttle it?

Cleaned the gas tank, installed a new carburator, installed a gas filter. Starts good, idles good but dies when I throttle it. I am at wits end as to what the problem is. I would appreciate any advice on what to check….Thanks

Why does my bike bog from quick throttle openings?

We’ll look at poor jetting in a minute, but let’s look at the other reasons why your bike bogs from quick throttle openings. An accelerator pump is simply a device (usually mechanical) on a 4 stroke carb that shoots an extra amount of fuel at low RPM throttle openings.

Why does my bike lose power when I idle?

Again, if you ride a modern bike you’ll have no idea what a choke is, but even Electronically Fuel Injected motorcycles reveal a lot by “blipping” the throttle. Rich bikes are getting too much gas, so they idle high but lose power when given initial throttle because they can’t burn all the gas.

What happens when you hit start on a bike?

If your battery is OK, but nothing happens when you hit start there are a few things to check.

What causes a motorcycle engine to lose power?

A vacuum leak leads to too much air being added to the air-fuel mixture the carburetor makes. When your motorcycle engine is getting too much air and not enough fuel, it won’t run right. In fact, the more gas you try to give the motorcycle, the more air will be sucked into the unwanted holes which will ultimately make you lose power.

Why does my motorcycle accelerate faster than my carburetor?

The previous stated solutions to your accelerating problems only apply to motorcycles with carburetors. If you have a fuel injected bike with acceleration problems, your likely culprit is poor timing advance. The faster you go on a motorcycle, the sooner your ignition coil will tell the spark plugs to fire.

Why does my bike die when I start it?

If you can start and idle fine, but slowly rolling on the throttle bogs/dies, that’s the culprit. If you can make it through the bog and then it suddenly roars to life, that’s also a really big confirmation as well.

What causes a motorcycle to not start up?

One potential issue that might be keeping your motorcycle from starting up is a clogged petcock. The petcock is a fuel control valve. It controls the gas flow between off, on, and reserve settings. Clogged petcocks are a common issue that riders often bring up in forums.

What causes your motorcycle to bog down when you run out of fuel?

Lean Bog – This is caused when there’s too much air and not enough fuel in the engine. You’ve probably experienced this bike acceleration problem when you run out of fuel on your motorcycle or if you’ve opened your airboxes. This feels like hitting the kill button on the engine for a second.

Why does my motorcycle keep running out of power?

A usual culprit to running problems on a motorcycle is the carburetor. Unfortunately there are a lot of things that can go wrong with a motorcycle carburetor, but luckily they’re pretty simple to work on and fix. If you’re having acceleration problems, the first thing you’ll probably want to look at is the jets inside the carburetor.

Why does my Chainsaw choke when I give it gas?

You have probable ethanol fuel related gumming which is causing the inlet valve to stick open and flood the engine , do you have a manual fuel shutoff ? if so ensure to use it . Get some concentrated carb cleaner and add 2 ounces to your FRESH Fuel . Let it sit for approx 20 minutes . Then attempt to start the engine without choke .

What happens if your car runs out of fuel?

If the supply lines break or are clogged for some reason, your car’s engine can shut off completely while running. If you are driving around without keeping an eye on your fuel gauge, there is a higher chance that your fuel will run out and you could be left stranded on the side of the road.

Why does my Traxx die at full throttle?

Click to expand… mine also bogs out and dies at full throttle but that’s ONLY if you give it full throttle. Also I’m not letting it warm up a little before giving it full gas could that be the problem?

Why does my Chainsaw die when I give it gas?

If it was running fine, I’d let that fast idle go 30 sec or so til warmed up, then pull the throtle which kicks off the auto fast, and it should drop into a normal idle mode, ready to start cutting. But now the auto fast stage seems a little fast (maybe not).. When I give it any gas it dies almost instantly.

What to do if your engine dies when you release the gas?

If the engine runs fine when you are holding the accelerator pedal down and dies when you release it then you may have a couple of possible issues. I would first check the vacuum hoses going to the engine. If any of them are loose or leaking, this will occur. If they are fine then the throttle body should be cleaned.

What causes a weed eater to die when throttled?

The most common causes of a weed eater dying when throttled are fuel issues, insufficient air intake, or problems with the exhaust. You should follow the path that the fuel travels to identify the issue.

Can a bad throttle position sensor cause idle surging?

Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light
