Yes, it is generally recommended to use anti-seize compound on motorcycle spark plugs. Anti-seize is a lubricating substance that helps prevent the spark plugs from seizing or sticking in the cylinder head due to heat, corrosion, or other factors. It also facilitates easy removal of the spark plugs during future maintenance or replacement.
When applying anti-seize to spark plugs, it's important to use it sparingly and apply it only to the threads of the plug. Avoid getting the compound on the electrode or the porcelain insulator, as it can affect the spark plug's performance. Additionally, ensure that the anti-seize compound you use is specifically designed for spark plugs and suitable for the high temperatures and conditions encountered in engines.
Always consult your motorcycle's owner's manual or a trusted mechanic for specific recommendations regarding the use of anti-seize compound on spark plugs, as different motorcycles may have different requirements.
