How To Tell If Stator Is Bad On Dirt Bike

If your battery is less than 126 V after sitting a few minutes your battery is shot. I am sure there are diferent symptoms as diferent areas of the stator can go bad.

Symptoms Of A Clogged Fuel Filter On A Dirt Bike And Atv Motosport

Unfortunately this can be caused by a variety of other issues with your ATV.

How to tell if stator is bad on dirt bike. If that happens then the wires short against the flywheel when its on the bike. You will need a multimeter set to Ohms for this test. My meter reads OL meaning over limit when there is no connection or infinite resistance between two points.

Saturday it almost killed me on a fast triple triple triple section. On a twin one cylinder fires and the other is weak or not firing. Stators tend to be reliable so before you go replacing the stator check on these other components.

How to Know if a Stator is Defective. You should read around 02 to 05 ohms. If all of that looks and tests great but still no spark take all the pieces down to your nearest bike dealer and ask them to test those components.

Spark plugs keep getting richerdarker as the day goes on indicating weakening spark. If it only a little low you may be able to rejuvenate your battery with a product called Battery Minder. Insert each probe into a stator socket.

Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced. If your stator is bad your battery will not charge while youre driving the ATV. Best thing to do is test your unit with the ohms meter.

Repeat for the negative diode by connecting the positive lead to the negative diode and connecting the stator inputs and negative lead. If the bike hasnt been charging at this point you need to test the charging system components. Have you tested the stator.

It felt like it was only firing every other time. Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced. Its often pretty obvious when you need to test or service your stator because its breakdown results in charging issues that result in issues like poor ignition performance dim andor flickering lights and ultimately the bike being unable to start.

Weak orange or yellow spark. This is common with old British style rotors. Look closely at the wires on the stator.

A bike with CDI ignition may have a 2 part stator where most of the windings generate power to the battery via the Recreg and have another part say two coils that power the ignition Sometimes it may be just the generating coils that fail sometimes the CDI source coils. It would sputter and act like a bad spark plug and then just die after a few minutes. The reading of each combination should be the same test leads 1-2 2-3 and 3-1.

If left on a metal table or allowed to collect metal hardware while sitting they can lose some of their magnetism. To check the regulator connect the meter leads to the bikes battery as its running. If there is any resistance reading 0-100 ohms then your stator is bad.

The most obvious symptoms of a bad motorcycle stator include no spark weak spark or intermittent spark also known as misfiring. It would start perfectly and idle decent but when I would give it gas it seemed like it was hitting a rev limiter. Visual inspection will tell you very little about its actual electrical condition.

Motorcycle Stators play a crucial part in starting and powering your machine but how can you tell if it is bad or not. If you have the equipment rotors and flywheels can be recharged. On a triple 2 cylinders are firing but one is weak or does not have spark.

The meter shouldnt show any reads when you connect the positive lead and stator inputs. When the bike gets hot around 10-15 minutes of riding it has an intermittent bog on the top end. If these tests all produce positive results then the stator itself is good.

A bad stator can also give the same problems too. Not too many shops have that equipment. If you show an open circuit with the Open or infinity reading or have higher resistance then the stator is bad and you must replace it.

Remember if you go out and spend a bunch of money on electrical parts and then you find something else. You said the screws were loose. If they were loose enough for the coils to move around they can touch the flywheel and some of the wires get cut or some of the coating rubbed off.

Sled slowly loses power during the course of the day. Testing for continuity through the stator wires is where I start when testing a stator. You dont have to take off your cover just attach redwhite and ground the other probe and make sure you zero out your ohms meter first.

In this video we demonstrate how to t. Many times stator problems are falsely diagnosed to other areas. Test every lead of the stators connector and note the readings.

To be honest the loose stator couldve been why you had no spark. Again with the bike turned off test the resistance between each stator leg and a chassis ground. If you know your bike pinning down the culprit is pretty quick and easy.

In most cases a CDI will just plain fail and thus no spark but I have seen one or two that would give good spark for starting but would not allow the engine to rev. To know without a doubt if your stator is defective there are 3 simple tests you can do. You should see infinite resistance no connection at all.

If the voltage really drops like 115 volts then either your stator or the rectifier is bad. The most obvious symptoms of a bad motorcycle stator include no spark weak spark or intermittent spark also known as misfiring. Yes a flywheel can lose its magnetism.

The only bike that I have dealt with that had a bad stator was a 2006 RM85. Right before the last triple it bogged hard under full throttle leaving the face and wouldnt rev in the air to keep the front end high so I went into a gnarly ass puckering mid air nose wheelie. KTM stators have 3 coils the main one gives voltage to the lights etc as the Beta can work without a battery this one was not part of the problem the next one is the exciter coil this provides the spark with its energy the final coil is called a pulser it tells the CDIs when top dead center is so it can get the timing right these go most regularly.
