I have a 2001 aerox, it had a the pm tuning 70 cc kit, pm tuning full circle crank, 21 mm carb, and a few other things.
The other day i was just riding down the road and it snapped a brand new drive belt any ideas why ? all i can think of is inperfections in the belt, or simply it couldnt cope with the power of the 70 kit so i bought my self a hebo belt and it has now ruined my variator, melted every roller, there was no warning for this happening just a sudden loss of power whist doing this it hqas rounded all the splines in variator and made the hole more of an oval,the variator is older than all the parts but it was a dopler one and it had just had new rollers any ideas ?
