I am on a mission for my sister in law. She has to replace the spark plugs in her 1984 sportster, it is a 1200 cc engine and I hav e looked on other sites and cannot seem to find the proper spark plug type for the bike and was wondering if any one can help.


Thank you

Humm. You got a keeper since Harley dident start make the 1200 Sporty till 1988. If in fact its a 1984 Ironhead the pulg should be RL82YC Champion or try a SF-412C Split Fire.
