I come to you as SF's are not my norm.

I have here a smallframe with engine VMA1M012607 which makes it circa 1966.

This bike is absolutely coming out of 4th gear all the way down the street.

I believe a later gear mechanism for PK type was installed; measured 50.2 and is curved.

Correct me if I am wrong here- doesn't this gearbox take the 51mm, angular type? Piaggio #111589

Check what marking the loose gears have.
Starts with:
• 42 - PK type and 50.2 mm selector
• 37(or no marking at all) - PV type and 51 mm selector
