I've searched about the threads but can't seem to find a #.  Snidal lists .018 - .020" for the gap on a "500 cc" but I'd love to confirm that with the Electra manual recommendation.

Could someone please let me know if that is correct?

Thanks.

I have the Super Factory Manual for the Electra and it says the spark plug gap should be set to between .6 and .7  (.65) but i'm not sure if this is metric or SAE or what... maybe someone with actual experience can confirm.

.65 mm = .0255 in.

Oh - Ok.  Interesting.  I'll adjust to that.  I wonder if it will make a difference.

Thanks for the #'s guys.

        Chuck, c'mon. Think about what you're saying.

         How could you possibly gap a plug at 0.6 to 0.7 of an INCH?

          Of course it's Metric (millimeters).

Used to kknow a guy I was trying to teach a few basics to...  He was trying to get an old engine running.  He finally got around to asking about plug gap and I told him.  He calls back and says he doesn't have this "guage thing", so I tell him he can get sorta close if he uses a thin dime.  "oh... OK"

"Hey Ernie, I'm trying to start this thing but it just won't catch" 
 
So I go over and the electrode is sticking almost out straight.  I ask him what the hell was he thinking?!
"Well- I didn't have a dime, so I used the next best thing!", he says all proud.
Yeah...?

Ernie, even if if not true, it's a great story.
