Piston Rings 69.5mm
Posted: Tue Nov 29, 2011 2:17 pm
Can anyone help? I'm after rings for these 69.5 mm pistons.
I have four 69.5 mm pistons.
They have ART embossed on one of the sides and 108 on the other. They are domed and are probably 10:1 compression.
The ring sizes are :
Top Ring ..... 1.0 mm thick (nom).
2nd Ring ..... 1.2 mm thick (nom), with the recess on the inside and facing up.
Oil ring (3 piece) ..... 2.45 mm thick (nom).
Where will I get rings for these pistons? Any suggestions?
Noting that the usual 70 mm ART pistons in Z1000's have a 1.2 mm top ring with the others about the same, as above.
Regardz.
