Need a piston...

Hey guys, i dropped a valve in my YFZ and i am looking for a stock WR450 Piston to put in since i have a WR crank, anyone know where i could find one for cheap ? new or second hand.

Thanks !

LOL, you do not want a used piston. TT store will beat any price you can find for a legitimate new part. If your old piston is shot, what condition is the barrel? Is your rid ok? You know you must have rings too as well as gaskets, probably should do a timing chain

Thanks guy, i will buy a new one, my cylinder is just like new, it only damaged my head and the piston... now thew only thing is whats the difference between the 03-05 and the 06-09 piston kits ? it would probably be the gaskets... idk wich one to order for my 05 YFZ.

See below. The wr and yfz piston are the same part number. I'd get the '05 YFZ Piston. Its much cheaper. 09s are the same.
