My brand new 2007 Vino 125 has something seriously wrong with it! I've done less than 800 k' on it in the 3 months I've had it. All of a sudden I notice it's oil levels dropping for no reason [no evidence of a leak - no drips etc]. I refilled the oil as per the manual [even got Yamalube!], the next day I had a total loss of power, couldn't get more than 40 kph on anything above a slight incline. So, I've taken it back to the dealer as it's still under warranty for repairs. I'm just really concerned this could be an on going problem or a known issue. I haven't thrashed it, I only use it to go a max of 30 k's a day in peak hour traffic & I weigh 90 kilos. Anyone got Feedback? Thoughts? Ideas?
