BMW Motorrad Spark Plugs Buying Guide
What BMW Motorrad Spark Plugs Do
They ignite the mixture of oxygen and fuel in your bike's engine. That's how the combustion process starts, and how the engine produces the power it runs on.
How BMW Motorrad Spark Plugs Work
The process, called spark ignition, involves an ignition switch, the battery, and a few other ignition parts. Together, they generate electricity, a charge that the plugs' leads pick up. Combustion happens, and your engine pistons, the crankshaft, the alternator, and more start running.
How to Spot Faulty Spark Plugs
Besides corrosion, physical deterioration, overly wide leads, conductivity problems, and outright breakage:
- Hard starts
- Worsening fuel economy
- Engine misfires and backfires
- A flooded engine
- Smelling gas at startup
- Gas spraying out of your exhaust pipe
- Idling roughly
- Having problems accelerating
When Should They be Changed?
When you notice these signs, or if you inspect your motorcycle's engine and the results recommend replacing them. Play it save by checking them every 4,000 to 5,000 miles and take care of the job before they exceed their suggested mileage limits -- around 8,000 to 10,000 miles. Most importantly, if you're looking to order new ones, be sure you get the genuine article.
