My “06” Brute Force 750 is back firing thru the carburators and will only idle with the choke on. It’s been setting up for several months. What’s could be the cause and cure ?
Experienced athletes share their insights in answering this question:
Sounds like you may have to do a complete carburetor cleaning. Also, after this is done, be sure to put the breather box back and that includes the box cover. That bike is not worth a fiddlers, ….. without that cover put back on it. If the carburetor cleaning is not done properly then you’ll still have the problem. Also, be careful when taking the carbs apart, they have different size jets in them and don’t move anything in regards to linkages. Those carbs are also syncronized.

If that don’t do it, then maybe, you’ll need your valve clearances adjusted.

Good luck

How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

Assuming all of your plugs and wires are in the correct locations and you haven`t messed with the timing at all, then the most common cause of backfiring through the carb (spitting or coughing) is in the morning when a carb`s air/fuel mixture is a bit too lean. This usually goes away once the engine warms-up.
How much horsepower does a Kawasaki Brute Force 750 4x4i EPS have? The Kawasaki Brute Force 750 4x4i EPS has 50.00 HP (36.5 kW)) @ 6750 RPM.
Kawasaki`s Electric Power Steering (EPS) system is designed to enhance the handling and ride comfort level on the Brute Force 750 4x4i EPS. Turning the bars causes a signal to be sent to the electronic power steering control unit, initiating power assist.
Another possible cause of your backfire is a spark plug refusing to “spark” when the exhaust valve opens. If the air/fuel mixture has become too rich, unburned fuel is left in the exhaust system. The misfired spark plug ignites the rich air/fuel mixture, causing a loud “bang” in the tail pipe.
Backfires

Touching back on air to fuel ratios, a vacuum leak will likely make your engine run “lean” (too much air.) This means the engine cannot efficiently ignite fuel in the combustion chamber. When fuel builds up in the cylinders and combustion occurs, it will expel a backfire.

From memory 7.5:1 = about 145–150 psi, 8:1= about 150–155psi 8.5:1=about 160 -175psi, 9:1=about 180–190psi and 10:1= about 190–210 psi.
This is a Kawasaki Brute Force 750cc Piston Kit with a compression ratio of 12:1.

Lets take a look at what it offers: Supplying power to the ground is a 401cc air-cooled single churning out a mind-bending 13.5-horsepower.
The Brute Force 750 chassis utilizes a double-cradle steel tube configuration designed for nimble handling and long term reliability. Five-way, preload adjustable shocks do a good job on most trail obstacles although it is possible to bottom the suspension when riding aggressively over rough terrain.
The VN750 was unique in its class by featuring a more reliable shaft drive usually found on larger cruisers. The motorcycle also featured a liquid-cooled DOHC V-twin engine producing 66 horsepower and 47 ft-lbs of torque. Notably, the torque curve is quite flat, producing high torque throughout most of the rpm range.
V-twin power is fantastic, and while Kawasaki isn`t forthcoming with horsepower numbers, we know this engine packs around 50 ponies. It`s a strong engine and highly reliable mill that produces minimal vibration due to a 90-degree cylinder offset.
Backfires and afterfires are worth paying attention to since they can cause engine damage, power loss, and decreased fuel efficiency.
On the other end of the spectrum, a bad fuel pump, vacuum leak, or clogged fuel injectors could cause an air-fuel ratio that`s too lean; that is, it has too much air and not enough fuel. Though this is the opposite problem, it can also cause a backfire as vapor escapes into the exhaust and combusts there.
Lean Air/Fuel Mixture

Not only can a rich air/fuel ratio cause a backfire, a mixture that doesn`t have enough gasoline can cause a backfire, too. A “lean” mixture is one that doesn`t have enough fuel, and too much air.

Sometimes, your car may have the following symptoms: an irregular idle, poor fuel economy, lack of power, stalling, or a high-pitched hissing sound from the engine.
The generally accepted gauge for adding compression is that one full point of compression can add between 3 to 4 percent power. So, if an engine is making 50 horsepower and we add a full point of compression (from 11 to 12:1 for example), this could potentially push the power to 51.5 horsepower.
Numbers higher than 200 psi create excessive cylinder pressure at low engine speeds, which turns the engine into a detonating monster.
Determining the Right Octane

The compression ratio of your vehicle is from 9:1 to 10:1, you can use 90. octane. The compression ratio of your vehicle is from 10:1 to 11:1, you can use 92.

For all the above reasons, we would never recommend a 10:1 static compression ratio with iron heads and a short duration cam for towing. Another area worthy of consideration is how inlet air temperature affects how quickly an engine might experience detonation given a fixed octane fuel.
Generally, engines with compression ratios of 9.3 : 1 or less will safely operate with unleaded 87 octane fuel. Engines with higher compression ratios usually require higher octane fuels. Many owners who operate vehicles designed to operate on 87 octane fuel experience ping and knock.
At what compression ratio do you need premium fuel? Most gas stations offer three grades of octane, with regular rated typically at 87, mid-grade at 89 and premium at 92 or 93.
It has an octane rating (AKI) of 100 and can be used in engines with compression ratios up to 12 to 1 (with hardened valve seats).
These voltages can be anywhere from 40 kV to 100 kV, in other words high voltage. Spark plugs are an important part of gasoline engines, but not a part of diesel engines, since diesel is ignited by compression ignition instead.

05 750 brute force missing badly
ANSWER : Just had same problem. Take carbs off and clean all jets and bowl. Be carful front and rear carb have different sized jets. When you put quad back together put entire airbox together even the cover. This quad will backfire unless air box is complete. I bet you anything your carb is full of trash.

My vulcan 1500 1997 back fire somme time wy
ANSWER : Lean gas mixture. or the valve timing is off, but probably both. A lean mix will run really hot and allow for secondary combustion in the pipes (backfire) when the valves let even a bit of uncombusted gas through. My guess is that the bike hasn’t had the carbs cleaned out thoroughly in a while. Run a half can of Sea Foam with your full tank of gas to help clean out the carbs, but really you should take them apart and dip them to clean everything out. Also you could adjust your pilot screw settings to make it run a bit more rich, but then you are just compensating for the dirty carbs. That’s just my guess.

ANSWER : Try switching sides of the handle by holding the bell and reeling then screw it in on the other side of the real by just reeling in.
If that doesn’t work then take all the line out and reel in some new line the opposite way.

I have a mossberg 510 youth 20 guage i took to the silder for the safety and the piece inside fell im 99% sure i have the peice put back properly but there is a small spring that i dont know what do do with it fell out and i do know where from the slider just freely moves back and forth and think it must be somthing about the spring that is keeping me from being able to get this problem fixed i have been working on this for hours please help
ANSWER : It’s pretty hard to figure this out without seeing the exact pieces sitting in front of someone. What I woud suggest is that you take the gun into a gun shop, and have them help you identify where the spring goes. This is the safest thing to do, when in doubt, otherwise you could jam or otherwise cause some damage.
Perhaps someone will have a Mossman, and know your answer, but if you don’t get one, call on the guys that do it for a living.
Good luck, and hope this helps.

ANSWER : May need to check that your barrel is NOT loose, check it out and if loose get it tight;)

I have a 750 08 brute force vtwin. After it heats up it spits and sputters and looses all power just had a new fuel pump put on. It acks like its either gettin to much gas or not enough but it runs fine from cold start untill it heats up
ANSWER : This ATV has a fuel injection system. Since the injection system doesn’t have a choke to enrich the fuel mixture when the engine is cold , the fuel flow thru the injectors is increased. The measure in which the fuel flow is increased is determined by an coolant temperature sensor – in your case this sensor is either disconnected or it has failed.

The sensor is in the bottom left side of the radiator – it screws in there.
