Spark plug mods for more HP?...

Hmmmmm...someone posted this on another site supposedly a way to gain HP by modifying spark plugs. Anyone ever heard this?...or just a crackhead's wisetale? LOL.

...[[""A little trick I found that works, Free Horse Power.Modify Your Spark Plugs For Free Horsepower.
There are many gizmo's that have claimed power increases through out the years (Splitfire spark plugs, indexing spark plugs, etc).
Here is a modification that works:
Bend up the negative electrode on your spark plug and cut approx 3/16 off. File the sharp edges edges and bend the negative electrode back to your desired spark plug gap.
Essentially turning your spark plug into a side firing plug.
Gasoline does not explode in the combustion chamber, it burns.
Nitro is the only fuel that explodes.
With this in mind we must remove any obstructions slowing down the burn (the negative electrode)
Attention to detail will make you a winner or run better than others.""]]... hmmm...At any rate, mine will stay the way they have been for 40+ years!!!

I dont think I will bother with this idea

Not sure about this...... have thought about indexing em for a little better burn but not sure if its worth the cost and trouble.

Side gapping and indexing are both age old proven tuning methods and every little helps especially when racing and this is something I do on the Orient Express drag bike and on my road bikes.
Why spend tons of cash on your engine and then not pay attention to getting the most out the main component that enables it to run with a small mod that costs nothing at all .
Side gapping exposes more of the spark energy to the fuel and indexing positions that spark towards the combustion chamber centre for the most efficient burn and can add several horsepower.
Never bend the earth electrode to the extent the other websites poster suggests though as it will fracture and drop off.
Only bend enough to get the final required gap.
The shortening of the electrode is done without bending it , just use a junior hacksaw blade and be careful not to catch the centre electrode or insulation when breaking through.
Finish by trueing up with a needle file and then set the gap.

And what do you think the newer bikes use?!
Side gap plugs.

old drag racer trick before the splitfire craze hit. This one works but its a minimal gain.. one that was used when looking for every last bit of power. But like other poster said.. NEVER bend electrode. Cut it with dremel cut off wheel.
