Well I just ended up running 20x40 yamaha lube in my bike, but the noise it was making ended up getting worse. I went to the dealership and they told me that they have never heard a raptor make a noise like that(which made me feel even better). But the did say that the one part thats been a problem with the Raptors is the starter one way clutch assembly. It's not your starter but it's the gear that your starter turns which has a clutch in front of it. So if your bike starts making weird noises and your starter starts actting up get it into the dealership before your warranty run out, like mine. The part runs $280. from the dealership so if you dont know how to fix it and dont have a warranty anymore have fun. I just thought maybe everyone who owns a raptor should know that one part is probably going to mess up at one point or other. And let me tell you you'll know when it does cuz my bike sounds like *** riding down the road.
