can anyone help, i have a ntv 600 and when i run the bike on tickover it does not smoke but when i take her for a run and welly her a bit, i then see alot of smoke behind me, today i topped up the oil level in the engine to the level on the dip stick and took her for a run again and noticed black oil come out of the front exhaust gasket, can anyone tell me if the valve stem seals are gone or could it be piston rings, i checked the oil and the water when i come back of the run after she cooled down and the levels seem fine. any information you can give to try and find out would be good.
