Hi, I'm having trouble finding out information about this scooter. There doesn't seem to be a repair manual available. I have found out some info from Auto Data, such as valve clearances and some torque settings. I'd like to know where the timing marker is? I've watched a Youtube video that shows an arrow inside the casing, however that isn't on this one. There is a line on the outside of the casing, which is what I decided to use as it's the only mark there. I lined the "T" up with it and went from there, it looked ok as the two lines on the cam pulley were in line with the top of the engine. Is this correct? Are there any tutorials out for this model? Or service/repair manuals? It's the 2021 model and is different from the older ones, so any info would be appreciated. Thanks.
