Hi all, hoping just maybe some-one has a spare 75mm 10.5:1 (I think)piston for sale from an Arias Z1000J/GPZ1100B piston kit. I bought a spares bike with three brand new Arias pistons and one which the top ring broke ( from the looks of the other pistons and unmarked sleeves which show no wear I am assuming the previous owner did not do the ring gap and the bike let go on the first warm up or they were damaged on installation) I have emailed Arias with all details and no reply,. I am told by the OZ distributor Arias will only do runs of 4 pistons. So I am left with the option of buying 5 pistons or seeing if there is something out there.
