![]() If you have to put starting fluid or a splash of gas into the cylinder to get it started, then the fueling system isn’t working properly. Why does my dirt bike only start with starting fluid? Or you had a crash the last time you rode that broke the kill-switch. Maybe you removed the tank and when re-installing it, an electrical connection got disconnected. Did this problem just start happening today? Did you do anything to your dirt bike, such as:Īny number of adjustments could’ve caused a change. You also need to ask yourself if anything has changed since the last time you rode. The exhaust to be in good shape (relatively dent-free with proper seal and packing).Jetting tuned for your specific bike, mods and climate.A tightly sealed airbox/intake boot/carburetor.To start and run properly, your dirt bike needs: This usually happens when the engine gets worn out or the head gasket fails from getting too hot. Low engine compression can also cause: rich jetting, spark plug fouling, and low power output. When the compression gets too low, it can’t compress and combust all of the air and fuel – this causes a rich jetting mixture. When you have the right amount of fuel, air and spark, it’s time to check the engine compression. Whether it’s a pit bike bike or full-sized dirt bike, 2 stroke or 4 stroke, they all operate on the same fundamentals. Perhaps the plug is fouled and just not creating enough or any spark to ignite the mixture. If there is no spark, even in a dark room, the next step is to try replacing the spark plug. Slowly kick or turn the engine over (in the dark makes it easier to see) and you will see a small blue spark jump across the electrode/tip of the spark plug. “No spark” can be caused by a fouled plug, a loose plug cap, a bad wire, a faulty ECU, or a bad stator.īut first, let’s check to see if that’s the case, because no spark is not as common as the other problems.īy taking the spark plug out but setting it on the engine with the plug cap installed you can test for spark. If you have fuel, air, and compression but no spark or not enough spark then your dirt bike engine can’t ignite the mixture and it won’t start. This means that it’s mostly likely not getting: spark, the right amount of air, enough engine compression. If it still won’t start or make any kind of combustion noise, then you can confirm that it’s getting fuel but still not starting. Otherwise, you can try squirting some starter fluid into the carb if it’s easier to pop it off of the intake boot. On a 2 stroke, removing the spark plug is as easy as unscrewing the plug on most models.įor some 4 stroke dirt bikes you may have to remove the gas tank to access the spark plug hole. To confirm that it’s getting fuel, you can put a few drops of gas or starting fluid into the engine through the spark plug hole. Both of these options will get more gas to your carb and possibly give you enough to get it started,Ī shiny bike is no good if you can’t start Bike won’t start even with starting fluid Pro tip: You can either turn the gas petcock valve to “reserve” if it has that option, or you can lean your dirt bike way over almost onto its left side to get the gas onto the side of the tank that has the petcock. Even if there is some gas left in the tank, it may not be high enough to get down through the petcock filter and to the carburetor, but there’s a simple trick you can do to see if that’s your problem. It’s easy to forgot to add gas to your dirt bike tank, especially if you don’t ride very often. Have you confirmed that it’s actually getting fuel to and through the engine? From the gas tank, through the fuel line, to the carb float bowl, and into the engine, it doesn’t take much to clog a passage. 2 stroke has fuel and spark but won’t start In this article, I’m going to show you the practical steps I take to get a dirt bike running when it won’t start and how to start diagnosing the problem. Those are just 2 parts to the equation, and just because you’re getting fuel and spark doesn’t mean it’s the right amount. You want to ride but your dirt bike won’t start but it has fuel and spark.
