Why does my motorcycle engine keep sputtering out?
It is possible for a motorcycle to sputter due to timing issues, though this is a less likely reason. It’s pretty hard to have the timing randomly start getting off by itself and is usually caused by either someone rebuilding the engine and getting the timing off or someone tried to fix the timing themselves previously.
Why is my motorcycle ( engine ) misfiring?
There is a problem with the ignition system, causing a weak spark. The fix: If your vehicle has them, check and replace distributor cap, rotor, ignition wires, and spark plugs. Otherwise, have the coil packs looked at. There may be a fault in the computerized engine control system. Check engine control systems with a scan tool.
Why does my motorcycle not have a spark plug?
If there are any cracks anywhere on the wires, the spark will arc to your motorcycle frame because that’s the path of least resistance for the electricity and it won’t arc through the spark plug. With no electricity delivered to the spark plug, that will in turn cause that cylinder to misfire. You’ll simply need to get a new spark plug wire.
Why is my air filter on my motorcycle not working?
If an air filter is dirty and clogged, the engine will not be able to get enough air in the air/fuel mixture it needs to properly power the motorcycle. Air filters need to be changed out routinely and people often forget to pay attention to them until it starts giving them problems.
Why are the spark plugs on my outboard motor fouling up?
One of the most common issues with two cycle outboard motors occurs when the spark plugs become saturated with gasoline, and foul out. When it seems like no amount of replacement plugs can fix the issue, it might be due to a number of factors.
When do you know your spark plugs are fouled?
Most often fouled spark plugs are noticed when the engine starts fine, runs fine for a while, but then bogs down, starts to lose RPM, and dies. If this occurs a number of times after the spark plugs have been replaced, the engine is flooding with gasoline.
Why is my spark plug black on my Harley Davidson?
Causes: The causes of this can be anything from, a rich fuel mixture, too much choke, long periods of low-speed riding or idling in traffic, a blocked air filter or the plug’s heat range is too cold. If the engine is running lean then the spark plug has a grey colour but you’ll probably see some black deposits on there too.
Why are my spark plugs not working properly?
The most common cause of this issue can be attributed to incorrect spark plugs, so be sure to check that the right spark plugs are being used first. The other issue could be an incorrect gasoline/two cycle outboard oil mixture.
