I used a rigid hone so the cylinders are round and have less than .001 taper but are out to limits 3.1275 to 3.128. one of the cylinders has discoloration do to water in them. You cannot feel the discoloration but it did not hone out. New standard pistons and rings. Before honing they were 3.126.
What lower end vent valve works the best the umbrella style or the reed valve style? I have both so I could put either in.
Dirk.
