Hey guys I am heading out to the Big Horns and I am bringing my 04 Viper ER I talk to Port Yamaha and got the spec for riding in 8000 to 10000 Ft. And they said I didnt need any Clutching done just some rivets that they sent, I just want know if that seems right. They sent Me the jets,gear and these rivets could somebody let know if this is right, just want make sure before I head out so I have the right settings Thanks Alot Jesse
