i have a vibration problem with my viper mountain. only happens when im ridin about 30km or higher. took blt off reved sled up to about 7000 rpm but nothing. so it aint the motor. sled had a new belt on it since 3 days ago. problem only came today. i am thinking its the driveaxle bearing. i can feel it on each side of the running boards. anyone have any ideas what it could be?
