will this fix?

Ouch! Anything can be fixed 🤣

The engine was new, what is the second piston size that can be used?

There are no over size pistons - I'd be more concerned with the engine cases and crankshaft.

What do you mean the engine was new? What break-in procedure did you use? What were you doing when it blew?

The bike was new, if I rectify the cylinders, what piston size can I use, and if that is not possible, where to buy only the repair of cylinders and pistons?

Buy the pistons from Polaris - send them along with the cylinders to US CHROME in Fondulac Wi - click HERE for their work order form - about $150 per cylinder or check the price of new parts from Polaris.

I would give you more detailed information, but you are keeping it a secret as to the year and model of what you destroyed. If you are not a qualified mechanic, you would be money ahead to buy a rebuilt engine from N-Flow and finally, if the ATV was NEW, why haven't you contacted the dealer to invoke warranty?

It kinda looks like it was run or forced to turn over with water in it. ????

From the looks of the muck around that engine, it looks like it was a deep mudder and ingested water and muck a full throttle. That is some pretty old looking grease and goo for a new engine.

Was new? is that one day after warranty ran out? the right side looks like the piston on my Express 400L 2 stroker after the automatic oiler stopped working over heated and blow head gasket which hydrolocked the piston. not realizing what caused the problem I replaced what was obviously broke and it happened again. Hopefully you already know what caused this.

OUCH!!! That hurts looking at it. Good luck brother
