Why do I keep losing power on my ATV?
If it fails, you may get symptoms such as random loss of power, almost as if a connection is loose. Your dealer may or may not be able to verify that you have a faulty unit. A bad voltage regulator, causing a too high voltage to be run through the system, is a common cause of a faulty ECU/ECM.
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.

Is the 1997 Polaris Sportsman 500 losing power?
2 Answers My 1997 Polaris Sportsman 500 has a loss of power when driving. It starts up just fine and runs smooth but there is only about half the power it had the week before. It does not back fire. When climbing a hill or on flat ground it reaches a certain power level and that’s all.
What should I do if my ATV is running too much?
Once you have it running, you can adjust it. Never turn the screw more than 1/8 of a turn at a time. Turning it in too much will cause the motor to run lean at full speed and may burn a piston. Also, running too lean will cause a loss of low end power.
