How to gap a BKR6EKU plug

[boscoe99]

Not to argue, but Rodbolt's post #8 says otherwise (horizontal to vertical), although he may have meant different. Your post says nothing about horizontal or vertical.

Factcheck, are you guys telling the truth?

Just posting pics to clarify for the OP and others interested.

Now I'll go get a beer or two!

Great job Charles.

Fairdeal. Now where the hell is fairdeal?

You have a curved ground strap.

Your checking the gap between the entire ground strap and the electrode, SO the gauge would be parallel with the electrode(same gap from ALL parts of the ground strap)...

Your gauge should fit nicely inside that strap and electrode..

Thanks Boscoe!

428, are you clear on this now?

I had a mistake on first post with images (post # 26) and edited/corrected. S /b "Image of feeler wire gauge .024" vertical flush to circular ground electrode and center porcelain insulator. Measurement is within NGK specifications"
above last image.

It is clear, thank you guys very much.

why is it so difficult top simply look at the YAMAHA tech bulliten on setting the gap ?

Cause we (most of us) don't have access to Yamaha tech bulletins...

[boscoe99]

Why is it so difficult to simply follow the procedures that the Yamaha trainers provide when being schooled at the Yamaha school house?

Oh, Yamaha won't let Yamaha engine owners go to school there.

Yes they will, u got to pay tho.

Why is it so difficult to simply follow the procedure that Yamaha provides in the owner's manual?

Now the gap can be measured using the owner's manual procedure or the technical bulletin procedure. The results will be (should be) the same.

Let's now debate applying oil or anti-seize to the spark plug threads. From NGK

. Anti-seize

NGK spark plugs feature what is known as trivalent plating. This silver-or-chrome colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without the use of anti-seize. NGK tech support has received a number of tech calls from installers who have over-tightened spark plugs because of the use of anti-seize. Anti-seize compound can act as a lubricant altering torque values up to 20 percent, increasing the risk of spark plug thread breakage.

maybe Boscoe can post a pic of the tech bulliten.
I think it is in the 05-06 MTG.

I also use NGK plugs in the motorcycle. Same as above, their coated, and anti seize (aluminum head as well) is NOT used.

I suspect all their plugs don't use anti-seize either.
