I'm surprised it took a whole tank! Mine locked down after about ten minutes. When I took it in for the first service, they forgot to refill the oil after draining it. I got home and rode for a few minutes. I heard something and thought they'd just left something a little loose, so I was heading back to the house when it cut off...lol, luckily going downhill toward my Mom's house. I coasted into her driveway and pulled the dipstick. There was oil on it so I wiped it off and put it back in, pulled it out.....nothing, put it back in, pulled it out...nothing, screwed it down, screwed out...NOTHING! I grabbed a flashlight and shined in it, sure was shiny! LOL
I live about 40 minutes from the dealership that performed the service that day. It was around 4:30 and they close at 5:00 so I high-tailed it back and called em on the way to make sure they didn't leave. When I told the service manager that there wasn't any oil in it, he said "that's strange". That was NOT the response I wanted so I was fit to be tied and ready to lock him down when I got there. When I pulled up, he had a couple of guys get the raptor off the truck and push it into one of the stalls in their shop. A few minutes later he came back out and apologised. He assured me they would have it fixed asap and just kept apologising. He wrote out that they would give me extra warranties and that they would replace everything that could have remotely been worn. I could have demanded a new motor but figured that was just as good. I've never had a problem with it at all and I rode it very, very hard for a couple of weeks after that.
I always check oil after someone else changes it, but that day when I checked it I was still at the shop and just pulled the stick out, seen oil and put it back as I was talking to the shop guy. Evidently they'd never pulled the dip stick and wiped it either.
No body but me will ever change my oil again LOL.
