Why does my engine run bad with a fouled spark plug?
A fouled spark plug happens when there is more fuel going into the combustion chamber (engine) than it can ignite and burn. The top causes of a fouled spark plug are: We already discussed why rich jetting causes bogging. If you don’t fix that problem, it will eventually cause the spark plug to foul and make it run even worse.
Why does my bike bog from quick throttle openings?
We’ll look at poor jetting in a minute, but let’s look at the other reasons why your bike bogs from quick throttle openings. An accelerator pump is simply a device (usually mechanical) on a 4 stroke carb that shoots an extra amount of fuel at low RPM throttle openings.
Why is the choke on my 2 stroke engine stuck?
If it runs the same in both positions, then the choke is either stuck on or off. An engine that isn’t up to full operating temperature (180 degrees or higher) can’t ignite and burn the air/fuel mixture as efficiently.
Why are my spark plugs fouling on my KTM 85sx?
I have a KTM 85sx. Spark plugs are very easily fouled. I found that two or three spark plugs were needed to get through a day of riding. This wasn’t just a case of not riding hard enough, even while flogging it they seemed to foul. I was told that perhaps my Stator (generator) was buggered and was giving a weak start.
Are there any problems with my ktm85 SX?
I too have a KTM85 sx (2005 Model), it was fouling plugs like no tomorrow, I would have to carry several plugs just to get through a day at the track, even tried Iridium plugs. I too thought the young fella wasn’t ringing it’s neck, so I’d jump on it and flog it… but still fouled plugs.
What to do if your KTM is locked?
Quickly close throttle, pull clutch lever, hit kill switch and coast to a stop. Pull the plug out and look at it. What colour is the ceramic around the electrode.
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.
