Motor Vibration - This normal?

I just picked up a 2008 700xx with 50 hours on it. Granted the tires need replacing and hold no traction. We just got a blizzard here and when I drive the quad at the higher RPMS i get motor vibration and the quad isn't going anywhere partially due to no traction.

This quad is so much different then my Polaris Scrambler 850 in the amount of Vibration.


I just want to know if this is normal

If theirs only 50 hrs on the quad, the clutch would of really had to be abused to need replaced. My original quad probably see's 50 hrs per session and the clutch is fine.

Have you check the right inboard joint for play? That could cause high rpm vibrations. If I remember right, another user had a issue and only noticed when spinning tires a lot in the snow.

Yea so basically the vibration difference is the Large single motor, my scrambler 850 is a twin so there is very little vibration plus the seat is huge and thick to absorb any of it.

Update for math correction 8.33 hours per year!

Sounds like it needs a pretty good once over. I'd be greasing and lubing any and everything you can, to extend the life on the dry parts. Unless you think the guy that had it before did all this. I know there are a few sweet barn finds with little to no hours on these quads. A couple years ago someone sold one on here with (0) riding hours! Just purchased, upgraded and sat in the garage, only started and let idle once a month or so.

The original owner installed a hour clock on the quad from the dealer from day 1 so he could follow the maintenance schedule religiously. He was very anal. The quad is beyond clean.....
