It is the most commonly caused by the inefficiency of airflow, fuel supply or it can be the ignition to the carburetor. With a new dirt bike, there can be few situations and one of that can be driver error?

Why is your dirt bike bogging out?

Here we are sharing you some symptoms through which you can identify the issue of bogging on your Dirt Bike after having full accelerator so check these ones by one.

Check Air filter

The most common reason why the engine is bogging down when accelerating is that the air 12 mixture is inefficient or dirty. If the air filter has dirt in it or it is clogged it can also be walking down the engine. So you have to clear the air filter and check out it.


This really only applies to bikes with carburetors either a two-stroke or four-stroke. If you have a fuel-injected bike it’s most likely your fuel pump or your fuel filter.

why is my dirt bike bogging out

If your Dirt bike is brand new, you need to adjust the needle on the carburetor slide. For doing this find the carburetor through the panel under the bike. You have to uncover the carburetor which will expose the different parts of it.

All the slide out with the needle attached to it. Three notches in the middle. Move the needle up to the top slot and put it back. Carburetor out and understood the bottom of the carburetor and clean the ball.

A Dirt Bike can be encounter by a number of issues and tight valves are also one of them so if you want to understand the symptoms of tight valves of a dirt bike then you can read this article

Fuel Screw

Now check your fuel screw. The fuel screw is mostly located in the front of the carburetor. It is kind of hard to get to, so you have to lose up the carburetor and rotate it to get to that screw.

So when you get the carburetor tilted a little bit and then you will get access to the screw. Start out by checking how many turns out the fuel screw.

About 1 and 3/4 so that is somewhat in the range for where it should be so put it to 2 out and see if that makes a difference rotate. If everything will be fine then back it into place and tighten it up. Sometimes there is no issue on the fuel screw.

Spark plug

Now check is the spark plug not the issue for this? So pull it out wire brush it torches it to burn off any oil and see if that creates any difference. so plug should look good and should not have tons of oil buildup nor is it should be white or extremely black.

If it is indicating a rich or severe lean condition so the plug is all cleaned up and while that’s out doesn’t hurt to check the gap as well.

So now you should pull apart the carburetor make sure the Jets aren’t plugged up and also check over the float height and some of the gaskets and seals. there as well so if you pull the carburetor off the boots and tilt it, you should be able to get to the football screws and then you will get access to those Jets and check the float height.

Check the Jets

The first few things you should check out are the Jets. You will see the main jet right there and then you’ll see the pilot jet is right up inside this hole.

Pop those out and see if they’re blocked, the most common reason for a bike to bog is a clogged pilot jet. so the longer jet right is the pilot jet and any small piece of dirt or grit that gets in there is gonna plug it up and cause the bike to bogging out.

Next, see if Jets are plugged up, the easiest way to do this is to hold them up to a light source and if they’re clear you’ll be able to see light coming through them so then you can see how small that pilot jet hole is it is super tiny if you do have a plugged jet an easy way to clear it out is by using compressed air.

Check the Float Height

Now check the float height so you want the carburetor somewhat level and then pull up on the floats and then let them settle so right there they will settle but you don’t want them pushing down the pin at all so that would be pushing down the pin and right it is settled.

When you have the float settled right there in this position, you want to have the flipple line and the line on the floats parallel and it will look quite parallel so it needs some adjusting. To adjust the float height this little tab right there has to be bent up or down as it sits right.

How to fix Float Height

The float’s height is set to high since the floats and the flow Bowl line are not parallel. So you have to bend this tab upwards to correct that so it’s as simple as getting a small screwdriver and pushing on the tab right.

It doesn’t take much to adjust it’s a pretty weak tab so how floats can get out of adjustment is just overtime then bouncing up and down you know over many years that’ll throw it out of whack and then also when you’re pulling off the flow.

Bowl the floats and the bowl are pretty close to each other and if you catch the floats, when you’re pulling off the bowl it could set that float height out of adjustment all right time to check this float height. So once again you should pull up on the floats let them settle.

Make sure they’re parallel so you settle the floats right there and then they will look pretty parallel. Now put that carburetor back together if you do have the float height spec.

How to measure it you’re gonna go from the float wall mounting surface to the line on the floats so you have to get the float settled right there and then measure.

Before the float height was too high and letting too much fuel into the carburetor and a good indicator of that is when you tip the bike over a little bit fuel will run out of the bottom of the carburetor. So that’s when you have a float height too high and when it’s too low it won’t allow enough fuel enough carburetor and cause it to run lean.

In this case, the float height was set to high causing a rich condition and fuel would drip out of the carburetor when you tilt it the bike on its side before you put the rest of this carburetor back together.

Need to Inspect

Earlier optimal fuel screw position is about two to two-and-a-half turns out that’s about where you want it. The holes right there and then on the contrary if your bike runs best at say one turn out or half a turn out then you need to go smaller on the pilot jet.

Always make sure that Jets are clear and the float height and you still have a bog there’s a variety of other things that could be as well but these are just the most common scenarios.

So make sure you have fresh gas clean air filter if your bike has a fuel filter make sure that’s clear and what else could it be you could also check for air leaks or a plugged exhaust system.

Mods that will make your dirt bike faster:

Upgrading gearing

Upgrading gearing is pretty much going to be upgrading your sprocket and your chain there are many benefits to this but there’s one thing I got to say before you actually upgrade it you need to upgrade it to suit your needs.

By that I mean you can get a large front socket or a small rear socket to improve your faster acceleration or you can get the opposite you can get a small front pocket and a large rear socket to improve your top speed.


Let’s talk about four-stroke engine four-stroke is pretty much the same concepts and ideas coming from two strokes but they have a slip-on and also an entire system so you can replace either one depending on your needs also.

It’s a great way to reduce weight when your juice weight you get better handling and also better top speed in the acceleration.


Heavy-duty tubes or get moose bibs heavy-duty tubes are gonna be a lot thicker than the stock tubes and they’re gonna be way more flat resistant than any stock tube
out there so be sure to pick up some heavy-duty tubes for the front and back wheels.

Steering damper upgrade

Your steering dampener pulp enhances your ride handling when you come off the bump it’ll prevent the shake that way you don’t crash into a tree fall down and get hurt.

So it’s a vital upgrade for your bike so an example of upgrading your steering damper when you go off-road or anything like that and you go on a straightaway relatively smooth and you see an aggressive rough patch coming up.

You can adjust the damper to you’re setting the bushing you prefer and in other examples when you’re riding Super cross-trade away
small bombs and then big jumps you can adjust the damper on the fly and it’ll make the ride so much easier so you don’t crash.

Upgrade your skills

It’s probably your best thing that you could do and also is basically free, go and watch YouTube videos on the ride which have already shared with you.

Go out there and take a class on riding techniques go out there and hit a trail that you haven’t hit before your skills the best thing you could do because if you have a bike that has too much power and you can’t handle it or he’s only made it at first you want to upgrade your skills.

Because you need to have control of your bike you need to be one with your bike if you’re not you’re pretty much-spending money that you will never be able to actually take advantage of riding.
