What RPM should my bike idle?
Car, truck, and motorcycle engines For a passenger car engine, idle speed is customarily between 600 and 1000 rpm. For medium and heavy duty trucks, it is approximately 600 rpm. For many single-cylinder motorcycle engines, idle speed is set between 1200 and 1500 rpm.
How long can a motorcycle idle?
I just now noticed in the Owner’s Manual that it says on page 49 “do not let the engine idle longer than five minutes, or engine overheating and damage may occur.”
What should the spark plugs on a motorcycle look like?
Your motorcycle’s spark plugs can be very useful to diagnose running conditions in your engine. You can use the burn color of your plugs and reference the plug color charts below to determine if your engine is running rich or lean. Good running conditions: If everything is good, the spark plug should have a tan/light brown color.
What does a lean spark plug look like?
A lean spark plug will have little to no color on the insulator tip. Symptoms of running lean are overheating, bogging or loss of power, and delay of returning to idle from higher RPM’s. Rich spark plug color The image below shows a plug off a motorcycle that was running pig rich.
How often should you change the spark plugs on a motorcycle?
Spark plugs are an easy and cheap fix and can be done within an hour. You can ride your motorcycle for years until you notice it’s acting up due to bad spark plugs, but you should probably take a look at them before they start giving you trouble. Motorcycle spark plugs should be replaced every five years.
How does the gap on a spark plug work?
A spark plug has a relatively simple construction and is nearly maintenance-free, except for the adjustment (gap) of its electrode and periodic cleaning or replacement. Setting the gap on the spark plug electrode determines the voltage length and duration of the spark. A spark plug that has an improper gap will show certain signs and symptoms.

How do you change the spark plugs on a motorcycle?
A lot of modern motorcycles require removal of the fuel tank. So, before you jump into it, check a service manual for the proper tank removal procedure. Remove the spark plug wires by pulling, firmly, straight up. Insert the spark plug wrench into the chamber. After removing the spark plugs, inspect them for any signs of unusual wear or coloring.
Which is the best spark plug for a motorcycle?
Platinum spark plugs will last longer than copper and can handle higher heat without breaking down. If you ride hard, and your bike runs at higher RPMs, these might be a good choice. Iridium spark plugs are known for lasting the longest and performing well under harsh conditions, such as racing.
What should the color of a spark plug be?
Note that sometimes, depending on the fuel and additives, the color may be grey instead. If it is, light grey is acceptable. No color, or white, indicates a lean condition, or lack of fuel. Dark brown or black color indicates a rich condition, or excess fuel. Normal spark plug color should show a light tan on the insulator tip.
