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.
