ART piston ID
« on: August 21, 2013, 06:13:13 pm »
I have just found a yz400 barrel and piston and am wondering if anyone knows what size it is, it has the no 51005 on the inside.

Cheers Darren

If it's a genuine Yam piston it will have the oversize stamped on the dome or blank if std bore,if you tell us the piston or bore size the tuning fork gurus will be able to help more :)

Measure it?
510 is the prefix for MX400B and YZ400C, IIRC.
