The kit was put together by my dealer.
I think it are the parts of the previous GasGas TXT pro 200.
Cilinderhead has a top cooling water connection.
Exhaust pipe bolts rotated as on the previous gasgas cilinders.
Main jet unchanged
Idle jet from 52 to 48
Squish set at 1,5
Hello Guy,
Herewith the drawing of the flywheel old and new.
The weight old/new about 306/548 gram. Mass inertia will be more than doubled I guess.
Very happy with the mod, less stalls and still very responsive.

I did the same and put a 200 kit on a 2017 GG 125TXT racing.
Made a flywheel weight just using available space without a spacer.
Can send you the drawing that I made.
