Hey guys,the block on my z1a is bored to 73.5mm.I'm after a 903 block and pistons 66mm.I'd be interested in anything as long as it's stamped 903.Thanks

The block is scored,number 1 piston shot,so its a bin job.Keen for your block pistons.

this set is off my 1973 bike,its got a bit of surface rust on it but a hone would get it back to new,i would rather swap it for something a bit bigger in cc for my other project.i dont know what its worth cash wise,the piston im holding is the one i bought to replace the one that copped it when a valve dropped.
