piston brands is like oil brands, i aint touching that one with a 10' pole.

l have reused heads on 2 stroke MX race bikes after losing a piston when in a jam, however i would caution against this, if there is any tiny peices of ring debris imbeded in the head there is a possiblity it will destroy the mill again.

Before you replace anything you need to indentify why it went pop, otherwise its pretty much a given it will go again.
