This bike burnt up at 1600 miles due to missing oil, now at 3500 miles it's trying to do the same thing. Kinked oil feed line at the bottom of the frame was the smoking gun that we blamed it on the first time. Now I have an oil cooler and yet when I checked the oil this morning nothing registered so I drained. Black oil came out with shiny dust in it. Never a good sign. I figure around a 1/2 quart drained out. Can't recall the last time I checked the oil, but it was somewhere around 3100 miles. No dirt, all street, not much freeway. Seems to be fine, then all at once (so it seems to me) it decides to burn or dump oil. I have not pulled the plug yet (does seem to run fine, up until now anyway) and I want to do a compression test. Checked for flow in the oil lines and she is doing good there. I've never had a bike go through oil like this POS so I'm wondering some black sheep have a habit of doing this or I'm missing something.
