Hello, I have a problem I'm hoping someone can help me with. I have a 2014 KLR that I was riding on the great divide ride when it started to use a lot of oil, as in a quart every 50 to 60 miles. I was on the way home so continued to dump oil into it to get home and made it 60 miles from home after dumping 15 quarts of oil into it in about 650 miles, before it finally fouled the plug. The oil was being burned as it was smoking like a forest fire out the exhaust, I checked the crankcase vent to see if it was being sucked out and it was not, air cleaner filter was not oil soaked or extremely dirty. Up until the plug fouled the bike was running ok at highway speed of 65 mph at about 4300 rpm. The bike has less then 5,000 miles and has not been overheated or run low on oil. any ideas?

1) Check the coolant and see if a) level is down substantially, or b) coolant is fouled with oil.
2) Check the oil to see if the oil is fouled with coolant.
3) Then probably conduct a leak-down test to see whats going on with compression.

Broken oil rings could cause part of that, but I've never heard of a KLR burning through that much oil -and still running.

Glad you were able to limp home.

Using stock parts, a DIY re-ring job is about $150 worth of materials (rings, head/base gasket, fluids) and two hours time if you have a hone and the tools.

Worst case, get the 685 EM kit and never worry about oil usage again for 60k or more miles.

I will suggest the possibility of Broken piston ring Lands between the rings. Possibly from detonation or from Hydraulic Lock due to raw fuel in the cylinder from carb flooding.
