Take a look at your last post..

And, while you have the gear box apart, replace ALL the snap rings...  8-)

Hey Captain  :lol:
That broken part is for the kick start return spring.
Have it welded.
But before you do anything get a piece of coat hanger or heavy wire that fits the hole.
Stick the wire in the hole.
That way when it is tig welded you don't deform the hole size or plug it up  :-o

Hello.
Yep, I got the PM late last night but didn't respond because I was beat.
I have rode both pistons.
It is highly unlikely that you can feel a difference.
The biggest reason for the mod was cooling.
Stewart (The last speed record holder) developed this mod for the KX500 to decrease temps around the crown of the piston at sustained high speed WOT runs.
It does not make any HP but it will help keep the HP at it's peak longer.
There are other potential benefits such as better lubrication of the wrist pin ect.
So, should you window your piston?
Mmmm... for most it isn't required but it's not going to hurt a thing if you do but don't really need it.
On my next build I will be putting some holes in that area, but not a big hole  :lol:
