The starter makes a very loud/terrible sound while trying to start. I think something may be going out, anyone have any ideas about what the problem might be ? is this notorious for rappy's ? Thanks

 

I know that the 660's were notorious for transmission problems when they first came out not sure about the later model raptors...are you positive that its the starter when she cranks over and have you taken it apart yet to find out...I bet if you ask driverdoyle he will be able to tell you what it is since he owned a raptor and seems to know alot about almost every quad.

 

here is a site I found that has some useful info on it hope it helps.
