Yamaha YZ250B Standard Piston

[smalls717]

Im chasing a standard piston for a Yamaha YZ250b if anybody has one available?
The cylinder on the bike is marked as a YZ250a. it is a chrome bore? are the cylinders for the A + B the same?
Either way the bore needs rechroming so i need a pistion to send off with the cylinder.

i bought a piston from the US / e-bay. was supposed to be a 250, but it is for a 360.
if anyone interested that is for sale.

what size the 360 piston and how much are you after?

thanks

[smalls717]

I only measured it with a ruler just to confirm it wasnt the piston I wanted. 
If I remember rightly it was 80mm.
Im at work for the next few days, but i can mike it up when i get back to get exact size.
$40 if interested. I paid double that from the US but it will be wasted otherwise.
Thnx.

If it's a gen Yam piston it will have a size on the top......if it's std it will have .98 or .96 on the top.

[Rossvickicampbell]

if it's a 96 I will take it

I should have a spare YZ250B piston in my stash. Maybe we could do a trade depending what size the 360 piston is. Does the 360 piston have apart number? Call me on zero427 926 14nine, I'm in melbourne. Where are you? Big Al
