My flatmate dropped our VTR250 (again) in low speed manoeuvring and it was down on it's left side for approx 15 mins, not running until I could go help him lift it. I didn't start it again and left it for a day so the oil could settle. It now blows large clouds of blueish smoke. I assume that oil has gone where it shouldn't and will burn away in time. I idled it (1 day after it was dropped) for about 30 mins to get it warm and it still blows smoke. Does it just need a run on the free way to get hot and clear it out or is it possible that more damage was done? I have demonstrated the method of lifting the bike (it only weighs 150kg anyway) so at least in future it shouldn't lay down to sleep. No other damage other than a bent gear shift which I straightened. The exhaust doesn't appear to be of a type that can be disassembled so I can't really clean it out. Oil in sump is still clearish and doesn't look like it has fuel in it and the bike still starts instantly and easily and idles fine.
