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?
 
process of ellimination ,

1- try another belt and check the front a arm on the skid aswell
2- pull primary clean and inspect all components
3-secondary same as primary
4- pull chain case cover , a- inspect tensioner
b- pull the gears and inspect the chain and shaft tolerance
5- jack shaft bearings , roll jack shaft on a piece of glass
6- drive shaft bearings

ps. if you want to check to motor use a dial indicator on the crank
***** i remember once we had went troug h some slush and 2 of us had really bad vibrations all the way home , picked at the ice and it was ok next time out *****

well it aint the belt i know for sure because i have a spare, no the driveaxle bearing. not the clutch because it do not make the sound when i rev her up with the belt off, has to be either the chaincase or jackshaft bearing
 
well i found the problem. jackshaft is snaped off right by the jackshaft bearing colar. only thing that is broke is the jackshaft. the chaincase is fine!
