CF Moto 150 E-Charm vibration problem

[walt]

When I first accelerate, my scooter shutters/vibrates until it gets rolling. I removed the clutch and sanded the inside of the outer clutch housing and I sanded the clutch pads. This eliminated the shuttering and vibration at take off, but only for a couple of weeks. I am assuming my problem is clutch related. Would you suggest replacing the entire clutch and can anyone recommend a good replacement clutch? Thanks
