Just got mine a while ago, have about 600 miles on it. Changed the oil at 25, 220, 450. Going to change it again at 950, then every 900miles after that. At 450 I put in a rare earth plug you can get from Ebay, same size as Honda Ruckus. I have already lost a bit on my top end, gonna change to a Ruckus 795 belt now, instead of the 788 stocker.
