pro x piston

i dont know all the technical specs on which is better but i know for $10 more you can get a Wiseco most seem to be happy with they're stuff. and $10 could also get you a membership on your favorite place to ask Blaster ?s I:I
 
I know a guy that used to run pro-x pistons in his watercross sled and know he didnt have many problems with them but like Racer X said you mine as well spend the extra $10 and get a Wiseco because then you know your getting a awsome product.
 
Eh, it's still gonna be a 200 cc blaster...or 195cc

You can get the cylinder volume using simple math:

pi r^2 h is equal the the volume of the cylinder

Stock bore and stroke is 66mm x 57 mm

So, to get cubic centimeters

pi x 3.3cm^2 x 5.7cm = 195

With a 67.5mm piston or 6.75cm, it would be

pi x 3.375cm^2 x 5.7cm = 203.97....so I guess you may have a 205 cc blaster!!

The object of going boring the cylinder out is not to increase power...it is to get a fresh cylinder surface to hold a good seal.
