84mm piston in a '98 warrior

[CarolusRex98]

I'm thinking about getting a 84mm weisco piston for my 1998 yamaha warrior 350 will it fit and if so will it make faster or stronger or hopefully both

You can take a stock jug out to 85mm, and that makes it a 366. But personally I would look at the JE pistons. Their a bit better than the wiseco.

What comp were you looking to run?

The compression will add a little more torque but stronger... What?

What, what??

I would stick to the 10.5:1 piston if you wanna go to a 366. The 12:1 piston would require race fuel.
