The only way to make the MHR60 go like the 57 on a 60 is to fettle it. As you have found out once fettled the story can change entirely. What durations did you end up with?
Try it with a 1.2mm packer & head gasket to give
1 - 1.5mm squish

hi Norrie, are you based in York ? I'm currently putting a MHR on a Lambretta and would welcome any input on the "fettling" side of things.
