Sparkplug to coil location
 

OK, I need to know If the top middle coil goes the the left (front) spark plug or the right (back )spark plug?

Both leading plugs fire at the same time, so it doesn't really matter. Do it however your particular wires run best.

How would they both fire the same if the rotors turn at different times?

"the leading plug fires a second time late in the power stroke, which is called a "wastespark". The wastespark is done to simplify the ignition system by allowing both leading plugs to be fired "on the same channel" (one coil, one signal) . Basically, both leading plugs always fire at the same time, so there is an extra (wasted) spark during the power stroke."

Thanks every thing is clear now.

Sure, I always wondered why myself and this gave me a reason to look it up.

Does this mean the spark plugs go bad quicker than they should be if fired separately?... Sorry I am assuming that the life of Spark plug is set by the number of times it can fire. Correct me if i am way off~

yea it would effect life span ,thats why they need cleaning after2,5k,also does anyone no if its ok to run all 9s on a pretty much stock motor?

They need cleaning sometimes because of carbon buildup. Firing isn't a big deal... if it were, the trailing plugs would be less worn because they don't have a "waste spark" and the leading do.

If the trailing plugs had a waste spark, they would pre-ignite the next combustion step.

cleared that up nice one and what about runnin all bur9 plugs ?
