ATV Repair and Maintenance Spark plug wire ?? August 29, 2015 Have a 2009 500HO and the black wire pulls right out of the red Sparkplug boot , is this normal ? Was having starting issues and that seems to be the source . Starts fine when the wire is pushed in tight ! Just wondering Thanks Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
