here's one folks. we have discussed the little bit of black smoke at first crank. the smoke is not thick, but it is black. well, i changed my oil today for the recommended 4000 mile service. the oil came out very very black. i only have experience with cars and have not seen a new engine in a car put out black oil after so little mileage. is it normal for it to be black?

Yes! You have a wet clutch, so the clutch and the engine run in the same oil . As the clutch plates break down, the particulate gets in the oil and turns it dark.
