spark plugs position

Just a fly in the ointment on the benefit theory ,when I had my C109 Boulevard (twin plug heads)I took the plugs out for a fiddle and to check the colour for combustion performance , and found one of the plugs had no sign of an centre electrode, we looked at it through a high power magnifier they use to check diesel injector nozzles (a black art) and it looked like it had never had been there since new ,thinking AH! here comes a performance improvement with a new set of Plugs ,guess what not one bit of difference it ran exactly the same , it was running just fine for 8000k with one dead plug ,and just fine but no different with new plugs

on a plug test on fast fours mag when fitted new plugs to begin the test they found new plugs produced 1 hp less power so maybe the rounded warn plug worked better and the long life plugs did not perform the best but the cheapest copper core ones produce the most power

Come on guys is this April 1st or something? When cruising the plug is firing at least than 1 second intervals. The mixture in the combustion chamber is a compressed gas which will ignite with one spark and we have two!

The bike has fuel injection monotired at many times more than that with sensors to make sure only the correct amount of fuel that can be burnt is injected.

Weight has got to make more difference surely? Therefore shouldn't we be arguing if we've taken a pee or had a dump before we go out if the power to weight ratio has made a difference? Will that difference be greater than point gnat's *****of a horsepower?

I remember reading about this awhile back, never really found out if it made a difference. He marked his plugs with a magic marker to assure the alignment. This kid must have read the same article,it's out there somewhere if you feel the need to research it. Now all we need is a diagram of the position of the valves...

But aren't you worried Pete that you could maybe loose .1hp? And even worse, that you mightn't even be aware of it. Are the potential gains really worth that risk?

One cylinder out?!
You, M8, have no sense of speed and power!
