Probably not. If the relaxed spring was shorter to begin with and it
was fabricated from coil wire of a thinner diameter, then the spring
could be compressed even further before reaching coil binding. Look at
the relaxed spring and call it dimension "A". Now stack a ton on it and
watch it compress until the coils touch. Won't go any further. Call
this dimension "B".
Although I wouldn't have any idea how to do this, you need to measure
the lenth or distance of the hollow space between the actual flywheel
and the floating pressure plate (not the floater or idler plate). You
need this distace from the bottom of the cast spring recesses.
So, if we had this space dimension, it had better be MORE than the
dimension B of the bound compressed spring. Otherwise, the spring locks
at bind before the clutch ever releases.
I don't know the space dimension or how to measure it. Surely there is
a way. However, Guzzi does publish dimensions for the springs. I think
their dimensions specify a certain length when compressed by a certain
force. Not sure how to apply that to our spring binding discussion.
