In before the lock...........A torque wrench is the way to go; however, if using an alternate method like 1/4 turn further when seated just know that you may get that slipping feeling of the aluminum threads giving way as you just try to give it a little more. Those of us who have been mechanics for a while (40 + years) know the feeling and then the process for installing an insert to correct the thread issue.

Or the next time you remove the spark plugs for "a look" you just might bring some of the aluminum threads out with the spark plug - no mechanic wants to see that and most of us who have worked on motorcycles do not want to see that, but it happens from ham fisted a plug in place by the owner, then having to explain to the owner his threads need an insert. Of course the owner will deny any such action so perhaps take the information provided under advisement.

Having a little thicker skin when asking question on a motorcycle forum is always a good thing, all information is worth what you pay for it. Best regards and ride on.

 

I have never used torque wrench on a spark plug going all the way back to my hot rod small block Chevy days and have never stripped a plug. I am trying to help you integrate into the forum but if you prefer to hang on to the attitude. I can't help and you will continue to get poked at by other forum members. That's the last piece of advice I can give you; if you want to be part of the forum, you should know what to do.

 

Trex, your suggestion to "go back and read" sparked my curiosity so I did just that. I looked at your post history. Seems like you've got a bit of an attitude problem from the get go and have done your own share of bashing. Apparently, you've got this thing about Gremlin Bells because that seems to be your number one go to insult. Maybe try some new material. LOL!
And you also posted once about the possibility of you cross threading a spark plug and wanting to use a long bar to remove it. How did you install the plug then? You apparently can buy tools because you mentioned buying a thread chaser and taps. I believe you just need to calm down and think before posting and ranting or insulting people. You'll get further. And yeah, maybe explain your problem or question a little better.

 

You know what else is wrong with him?
Apparently, he has no sense of touch.
Put them in as tight as your little girl arms will allow, Sport.

 

I clicked on his profile (that's where I found out he's handsome) and read some of his past posts. Seems to be a likeable fellow.... /S

 

I've never used a torque wrench on a spark plug either and I was wrenching on cars long before I could drive them. I've also seen more threads stripped by people with no common sense using them.
Never used antisieze on spark plugs either but then I don't use champions.

As far as integrating into this place, that works both ways. I can tell you there are people new to Harleys but far from new to wrenching or performance engines in general that never post here because of certain so called regulars. My inbox fills repeatedly because of them. One of the first to post here to no surprise to some of us.

Quick to throw the FSM in people's faces that ask questions about one topic , yet they toss it out the window when it comes to the next.
I'm all for having the fsm but in some cases it needs to be tossed out the window at high speeds. Perhaps this is one of them?

Now I don't know the OP as this is the first post I've seen of his and really don't give a $h!+ enough to look back at his others.

Just sayin'...

 

When reinstalling a used plug, after having a look at it, once it is seated hand tight, how much of a turn should it get, 1/8, 1/4, 180deg? This is in a TwinCam. That is hard to understand?

 

Not hard to understand at all.

But why is it hard for you to understand that many of us don`t see any of your choices as correct, and therefore are trying to tell you the correct way to do the job?

What exactly is your problem here, have the threads been damaged already and you are afraid that torquing the plugs to the correct value won`t work?

 

Dan....

 

really dude. He really may not know, or know how to take constructive information and apply it. If he comes back on here and says I tried to do three complete turns and f’’’’’’My head, that’s on you. And I hope everybody else on this form jumps on your ***. Quit giving bad information, or get off the forum
