Honda SFX 50 V-belts frayed and clutch hard to press

Hello dear community, I’ll get in touch again. I took off the Vario cover today and had to find out that the fringes of the V-belt were tangled by the wave of the Variomatik. The V-belt, which came new last year, looked quite taken away. That’s all apparently happened through the Malossi Multivar. Before the Multivar was installed the V-belt was still great. with the original V-belt and the 9gram weights the scooter also ran 80km/h. I was scared and nd wanted to rebuild everything immediately again, so I removed V-belts and installed the old variomatics with the newly acquired 9gram weights. During assembly the clutch could be pressed hard, so that I could easily push the V-belt onto the shaft from the Variomatics. That was not the case before, is now also the clutch or the converter worn out? now everything was rebuilt and could very hard push the V-belt back to the wave. was quite powerful. at the first test drive I noticed that the scooter was slower than before with the original variomatic. at that time the scooter ran 80, now it runs with the same setup 70. I’m not talking about the vmax, but I worry about the clutch. despite the malossi multivar, I never accelerated strongly or something. had bought it then as replacement and not to do.
