The MHR60 comes out tame, as it is similar to the MHR57 with the 1.5mm difference fixed at the head. 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.
