Kinda weird idea.... maybe?

So long story short I bough a spare af05 engine case so I can build an engine from the ground up. Ended up buying the spree version instead of the se50 one. (My fault, inexperience and lack of research). I was looking at the final gearing and noticed that it is different than my elite. So I decided to check it out. I spun the clutch shaft and counted 5 turns to one turn on the drive shaft. So here are my questions....

1. Is this better than the current SE50P gears I have now? (Looking for top speed)

2. Couldn't I also just bolt this right in with no problem?

Engine is a AF05 from 86 spree, and my scooter is an 87 SE50P

Make that 6.5 turns to 1. My bad

Those two engines have different transmissions





Top speed will be better with the se50 engine. (double reduction ratio trans).
