I have a question concerning the screw on type tips we have on
Our Harley Spark plugs.
My problem is I find when I go to check my
Plugs I find the tips loose, even though I
Tighten them with the aid of pliers.
Have you run into this also.
I was thinking of putting some red Locktite
Next time I find them loose.
Any ideas well appreciated.
Thanks!
NO on the loctite. It will act as an insulator.
I deform the screw on tip slightly with pliers,vise or a hammer. Only takes a tiny little dent. Better have a spare or two on hand. :SM:
won't hurt anything if they're a little bit loose, they're not going to come off and the spark won't know thw difference
if it really bothers you, hold the spark plug with a wrench or socket and then tighten it with pliers - I've never had one come loose when tightened that way
I "mung" the tip a bit when I tighten them, squeezing them to deform them slightly to keep them from unscrewing. Be careful not to knick the porcelain.
I also use a wrench to hold the plug to be able to tighten the tip tightly.
I don't use screw on tip plugs...
Just bugger the threads a bit before you screw the tip on.... will keep it snug
I Do the Same Thing. I Squeeze a Plier Gently on the Starting Threads to Keep the Tip Tight/Snug. I Have Done that On Many Other Things as Well, Inside and Outside of the H-D World.
Thanks All, I'll take your advice and deform the
Tip threads up a bit before I screw them on.
might be easier to install the post if you take a side cutter and deform the threads more towards the middle so the starter threads are not deformed.

With or without the motor running.

depends on your level of acceptable risk :)

That's what I've done over the years, especially with rigid wire boots
you can always tighten it till it breaks then back off 1/4 turn :teeth:

For far too long that was my method.
