Spark Plug Millimeter Measurement?
« on: June 05, 2006, 08:59:35 AM »
 I need to know the mm measurement for a standard spark plug that fits a 1970 CB-750. Is it 10mm? 14mm? I have to buy an adapter for my compression gauge and I want to be sure I have the right size.
Thanks...

The "D" in D8EA or D7EA signifies a 12 mm thread.  It's in the FAQ.

Uh...Thanks?  ???

I've done shorter ones, though.  I think it was the question about bolting a 750 engine into a 550 frame.  Can't get much shorter than "No".

Cheers,

Hey DL,
what year is you Wing. I picked up a 75 about a month ago and love it. It is all naked now, no bags or fairing. Plan on going to ride Trail Ridge road on thursday with a few on this board. Check out Nakedgoldwings.com
