I replaced mine for the first time at 101,050 and was shocked to see how wide the gap was; over .080, or almost double what they're set to when installed.
My understanding is that Vulcans don't have issues with spark plug threading. I could be wrong though. It's still entirely possible for them to be striped or seized in, but I've never seen or heard of it on a Vulcan.has anyone had any issues getting the plugs out of the heads?
