Yz will work but you must also use the YZ sleeve.

From what I know, thats not true.

I ran a YZ piston in mine for a little bit, a pro-x. I ended up switching back to the regular Wiseco pro-lite for the Tri-Z though.

The Wiseco weighs less then the pro-x YZ piston.

Thats what i heard several people say, so take it for what its worth. Supposedly the YZ piston wouldnt work with a tri-z sleeve (probably ports not lining up). :confused:

the mantis has a yz piston, and you all know it runs like a bat outa hell!!
i had a tri-z engine a few years back that had the yz piston in it, i know because the yz has no windows like the tri-z one, and i was like wtf!!
