I'm more back than new!

I have really like this sit thanks to all that help out and share.
  I sold all my bikes a few years ago and haven't been around much.  I have had a 450 for a while now but been missing 2-strokes and Saturday I did a quick search on Craig's list and a kx500 popped up in my town.  My heart about jumped out of my chest, called no answer figured it was sold since it was an old post.  He text me Sunday but we couldn't get together till Monday morning.  Anyway I'm the proud owner of a 2003 kx500.

Few questions,
It needs a top end I think (pulled exhaust and had black below the rings like maybe from blow by)
So are the Pro X pistons any good?
Do you need to drill any holes in the piston like on the CR500?
Are the cylinders bore able like the CR500 or are they plated like 250s?
I remember seeing the pistons on here that some one cut a window in, why? Do they have any left?

Thanks

I wouldn't.... get a Wossner...

No, but there are some really cool mods you can do with holes.

They are plated unless yours has been sleeved aftermarket.
You won't know till you get it off.

The school is out on that. Going back to holes in the piston there are some really cool things you can do with holes in the right place.

PM ALWARD25, he can give you details on a piston.

Thanks Sandblaster, I'll try and pm ALWARD25 this afternoon. 

Wossner =  Wisco?

Wossner is the brand name.  They make some very beautiful K5 stuff.  All the K5 guys on here swear by them.
