Picked up a 2016 gti 130 last week from a auction. Got it fairly cheap and expected something wrong with it. first test ride went well. Runs great and everything worked as it should. Second ride. I was idling taking to a buddy and it started to smoke (white) excessively. I took off and it cleared up. Seems to do it when i idle for 3 min or more. I checked the oil and it was low so it's definitely burning oil. Is there anything real common on these that could cause it? Valve seals? Has 250 hours Thanks in advance for any help. Edit. Ski runs great but can smell burning oil when following it on the water. I pulled the plugs out and 2 out of the 3 were soaked in oil.
