Post by: awaffa2003 on June 30, 2008, 08:36:23 PM

16 mm X 1.5, I believe. Not the standard thread.

Yeah, I had to go back to the Vapor manual and confirm the correct "pulse" setting for our R65s.

Remembering that the Beemer ignition "wastes" a spark on each cylinder; the plug actually fires on the exhaust stroke on one side as the other cylinder is firing on the power stroke.

I programed the Vapor for a "2 PPS" rather than the default setting of "1 PPS" and everything seems to read correctly. Tricky, since the coil fires both plugs at the same time... hence the so-called "wasted" spark. Left at the default setting, the tach's electronic brain thinks you're riding a 2-stroke. Horrors!
