Spark plug wrench

Recommended Posts

Just buy the correct size in a deep socket and have one of those mini magnet probes.  I’ve used that over a spark plug wrench for years.  For tightening, I gently unscrew until I feel the thread alignment pop…then gently hand tighten.  You’ll know right away if something is amiss.

It's an old trick to prevent cross-threading. Gently rotating the socket counterclockwise while aligned vertically will let you feel when the plug's leading thread drops a tiny bit into alignment with the head's first thread gap. It's subtle, and requires a deft touch, but it does work.

I’m glad I’m not the only one who knows that trick.  Works great when you have to thread a bolt by feel because you don’t have a good line of sight.  Mostly, I do this installing oil filters where I’m lucky to just get my hand in place.

Ahhh.  Yea, I've done it on some stuff.  It's not something I'd think about with a BB spark plug since it would take effort to cross thread it.

Do you really foresee changing a plug on the road?

Not in the next 20 or so years. :)

If I decide to sell one of the bikes I would want to give the new owner a spark plug wrench.
