Pfaff 130s were being bought up by the carload to take to India and
environs to put in factories where the machines are run off a central
motor, so I doubt that the machine would have a problem with a bigger
motor. It's an all-metal, all-mechanical machine, so it will go as fast
as you can drive it - though you should slow down if it starts to glow
red. ;-)
Perhaps Ron or gwh will turn up to comment on this, since they are the
resident experts in the field. I am sure that you can replace both the
motor and the controller, but I don't have the knowledge to advise you
on what you could use for the substitution.
