Hi. The problem is in a motorcycle row 110. I live in a small town and walking inside the town the motorcycle does not smoke long and goes well .. but when I go to the field and go on the road I make a kilometer and starts to smoke blue smoke . When I release the throttle, I have more smoke but white. Can the smoke be xq is the exhaust pipe dirty? Xq spent a while smoking and wasting oil while walking in the village ... now I changed the hoops and sent the lid to do, they told me that they changed the guides and valves .. I assemble the engine myself with little cooking and looking at youtube and in different forums. Any recommendation??

if it is white smoke it is because something is burning in the engine and the oil does not reduce friction

You may have to change piston rings kit and rectify cylinder .. changing rings only many times does not work
