Why does my spark plug not work on my bike?
If the plug has oil on it, then it’s oiling up and may not work efficiently, potentially causing a misfire or stuttering under hard acceleration. If it’s just dark or black the bike could be running too rich. A heavy accumulation of carbon on the nose can cause a leakage path to earth. This can cause misfires and poor engine starting.
What kind of spark plug do I Need?
Over-tightening can snap the spark plug – a nightmare. Don’t put any lubricant or thread lock on the spark plug. Inspect your spark plug caps and replace if required. A regular spark plug uses a copper central electrode whereas an iridium spark plug uses, you guessed it, iridium.

Motorcycle spark plug socket sizes are usually 16mm, 18mm or 20.6mm (21mm will do). Whereas the threads are usually 10mm, 12mm or 14mm. When it comes to motorcycles, access is usually tricky, so my tip is to buy a magnetic spark plug socket like this one.
Can a tapered spark plug snap a gasket?
Torque the spark plug up to your manufacturer’s recommended settings. If you don’t have a torque wrench, then get the plug hand tight and then add a ½ turn for a plug with a gasket, and more like a ¼ turn for a tapered spark plug. Over-tightening can snap the spark plug – a nightmare.
Why does my spark plug keep fouling up?

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.
