Rattling noise after 40 km/h

[hasi897]

So I have a kymco agility 16+, which by the way is so much nicer to ride than the normal 12 inch agility. However, it has a small problem, when i ride above 40 km/h I hear a rattling noise but drives fine under that speed.

My guess is a worn out or missing slider from the variator. Also how heavy should the rollers be? To me 7.5g feel too light.

I think you are probably right. You better check it soon because the issue of a worn slider can damage your variator. If 7,5 gram feels light I would have bought 2 sets of new rollers. 8,5 and 7,5gram. If 8,5 gram is to heave you can combine it with 7,5g.
