Different Contra Springs?

[MotoRandy123]

The Yager 125 uses 82mm or 3.2" contra spring (or movable face spring).
The Yager 200 uses 130mm or 5.2" contra spring.

I cannot find any specs on the aftermarket or GY6 generic springs
to know if they might give us a choice on the Yager?

It amazes me that people selling online do not give any info. Many times I
am looking for a custom solution and they say "Red Spring" or "For Jojo 50"
Why not length and diameter?

Maybe the People GT 200i or Downtown 200i have a stronger spring. Their engine is a full 30cc bigger than ours. I'm curious as to what might be interchangeable between the motors.

Well your right the People GT 200i and Downtown 200i both use a
LEA7 - E00 where the Yager is LEA6 - 900. Now If I could find a
service manual for one of those and see what it says for the length
of that spring.
