What are signs or symptoms that spark plugs in a motorcycle need to be changed?
Aug 06, 2008 by JamU | Posted in Motorcycles
Will the motorcycle "chug" when at say 55 or 60 mile per hour? Could this be because of spark plugs, needing to be changed?
There are several things that could hint at bad plugs.
- Hard starting.
- Slight to severe hesitation when you give the bike some throttle.
- Stalling, especially when you give the throttle a good twist
- uneven idling

Replaced the CR9E's with NGK's iridium version (CR9IEX) - there's a noticeable difference in the bike since but this is down to the general and suspected overdue servicing.
Changed the plugs today, seems I have an oil leak on top.

Right cylinder valves and spark plug. As you can see the bike was running very rich, or possibly burning oil. Hard for me to tell at this point.
