which one is by far hands down the best.

i was thinking wiseco, i need it @ .020 over

i also know that vitos makes like 4 different kits which are cast and forged also.

v581

 

I have wiseco in my banshee & blaster and they work fine... no problems here

 

If possiable, get a forged. They are more expensive but will last longer.

 

i would go with wiseco

 

alright thanks guys.

now the bike is a 2000, and is used, so i need to figure out exactly what size the cyclinder is.


the piston looks like a wiseco, and has a X on the top of it, i know if oversized, then it would have by how many mm stamped on top of it. does anyone know?

please help

 

I would bet your going to have a hard time getting any readings off a used piston....unless you can scrape away the layer of black that is probably on the top of it.

You need to get yourself a caliper and take some measurements...or drop the cylinder off at a repair shop and have them measure and check the bore for you.
