Downtown 300 / JCosta IT619PRO

Kymco downtown 300, 2009
I installed the JCosta IT619PRO variator. Everything is nice, the scooter works great on it but ..
when I lightly add gas, 8.5k rpm comes in and only gives back the speed as it is impossible to drive for me, I already thought that the grease came out of the corrector and something slips but not, everything is clean and the revs are flying like stupid ..
On the standard variator it was somehow better balanced here, a massacre. I don't know why the revolutions should be lower than on the standard.
It turns out that the skates are a bit too light. Now the question is, did anyone have a similar problem? Maybe someone will suggest the mass of rolls? It is quite a bit of a cost, because PLN 160 a set, but I have already spent so much that I would like it to happen somehow. Start 0.5g heavier or what?
