Hi, Welcome to Just Answer!
It is possible to figure out the gear ratio without pulling the cover.
Mark a spot on the tire/wheel and mark a spot on the drive shaft. Rotate the tire/wheel one full revolution and count the turns of the drive shaft. The number of turns of the drive shaft is the gear. If it turns 3 3/4 turns it is a 3:73, 3 and 1/2 turns is a 3:55 gear, Just over 3 turns is a 3:08, Just over 4 turns is 4:10, ETC
No need to pull the cover.
Jaxer i also know this. i am inquiring if stamp will give gear ratio?
No it will not.
