piet1977 10 Posted October 28, 2012 Hello everybody, I am the owner of a 2005 Kingquad 700 with 10251 km (6370 miles). I bought this ATV one year ago. Since I have this ATV, I have a high oil consumption. 20 fl.OZ each 150 miles. Therefore I decided to change the piston rings and also the valve seals. The ring clearance was out of tolerance. I did not change the piston and the cylinder. The clearance of the new rings are in the tolerance. After the change of the rings and seals the problem seems not to be solved. The oil consumption is still the same. The problem is that the ATV is not smoking blue (like oil burning). The sparkplug is coffe brown in the middle and black outside. The spark plug is completely dry. The coolant has a normal colour. No oil inside. There is no oil leak. The airbox is dry. The engine is starting and running normally!!!! I change also the oil type: 10W40 -> 10W50 Where is the oil going? I am sure that the oil is burned but why is the ATV not smoking blue ??? With this high oil consumption, I expected that the ATV smokes blue or the engine wouldn t run properly. My next step would be to change piston and cylinder.... I am confused and it would be helpful if somebody have a good idea. Share this post Link to post Share on other sites Like what you are reading? Please help us by sharing this content.
