"I also recommend cleaning/washing the CVT intake filter more often than 5000km otherwise it can overheat due to dust clogging. It's low to the ground so it gets dirtier than it should."
I can concur with that! I'm always suprised how dirty that little filter is when I open the transmission up.
I ride 300km-500km per week on my 300 and I change the oil every 3,500-4,000 km or so. It works out to around once every couple of months. I don't live in hot dusty condtions which I can only imagine would be a bit more harsh on the scooter, but I'd be surprised if it would really make much difference whether you change at 2,500 or 3,500. It's still well earlier than the recommended interval and should keep the scooter running well. It's a quick job and there's not that much oil involved in a change so it does't cost too much. Between the oil and filter it probably cost me $30 per change.
