saw an ad for a sooby for sale. haven't been able to look at it yet. ad says it makes black smoke. white usually coolant, bluish white oil. what is black? I haven't personally seen one do that. any one know off hand?

Black is running rich, too much fuel. Can be as simple as a tune up, can be a leaking carb..

it's an 88RX so it should be FI unless somebody swapped something shouldnt be carbed. ECU maybe in limp mode dumping fuel though.

OK FI then it can be leaky injectors.

Also suspect a leaking FPR.

Black smoke is managable and fixable. Its the heavy blue and white that require major work.
