hey guys, i am about to buy a new piston, pro-lite .060 ( 67.5mm).

First of all is that a good piston, and how many do i need?

and second how do I install one, and i cant buy a repair manual, cause im out of money once i buy a piston

 

What kind of quad are we talking about here?
If you are putting a piston in you will also need to purchase new gasket/s
It is important to know the torque of each bolt when you put it back together as well, a manual would be very benificial.
If you are running on stock bore make sure to get a stockbore piston... unless you are boring your sleeve.
