I got that information about the valve springs, from Piper for the Punto GT head you might advise me.

Spring ID 18.05 mm
OD 31.65 mm
Installed Lenght 37.1 mm

Do you think it would be wise to use these on the TIPO 1400 head?

Gary,

can you do two things please?

1. Post a good top-view photo of your cyl head.
2. Measure the tip height of one inlet and ex valve to the head (where the spring seat sits).
3. Give me the outer diameter and free length of the old springs.

Thanks

GC
