I have four top ends for sale. Includes the cylinder and head. Three need bored and one should just need a hone. I can get more pics of a cylinder if you are interested in one.
We will go from left to right in the pic above. The first cylinder has some light scaring and looks to be a 68mm. I think you should be able to squeeze a 68.25 since the scaring is light. May even clean up in a hone. Doesn't have exhaust studs. They have been drilled out and are using large bolts which will be included. $30 shipped.
Second cylinder has some scoring. I tried to get he worst spot in the pic. Looks to be a 67.5mm bore. $40 shipped.
Third cylinder doesn't have any scoring but has some surface rust near the bottom. The rust is light and should clean up with a hone. Looks to be a 67mm or .40 over. $45 shipped
Last cylinder is a 68mm bore. Ligth scoring in this one also. Should be able to squeeze a 68.25 bore out of it. $35 shipped
