My oil plug came out today on the dunes on my 07 raptor 700. Engine will not start now. It was making a whining sound like a worn out bearing. If worst comes to worst and I need a new engine about how much will that run me to get it running again and labor? Also if I need an engine any input on replacing it with a R1 engine. I do not know a lot about engine work so I would have to get an ATV mechanic to do this. Whats the cost I'm looking at with a raptor 700 engine as opposed to an R1 engine?
