Hi all,
The more I ride this bike the more I think that probably you guys are right. I'm used to riding a 50cc minarelli. There was almost no engine brake with that. This one is just too much. I've checked again the speedometer to see at what speed it pulls back and it seems to pull back around 10-15 kmph according to the speedometer. However it feels much lower speed than that as the speedometer reading is very delayed. I'm sure the bike is rolling less than 5 kmph at that point as I almost loose my balance when it happens.
I think I just have to get used to this.
I know the cvt system as I have worked on a couple of them, but they were all 50cc ones.
I've pulled off the plastic cover and the cast housing of the cvt drive. The outer side of the driven pulley moves nicely back and forth against the spring, so it is not the grease that sometimes get contaminated or dries out for sure. In order to know more, I need to pull both pulleys so I've ordered a universal flywheel tool.
Regardless, I now really believe that all I feel is the fact that this engine is much larger than the ones I'm used to and that's all...
