I have a 2004 700, and I have a vibration it starts at about 1800 rpm, it don't matter if i am in drive or neuteral.
after riding for a while the viration will numb hy hands and feet.
Any one have a similar problem.
I believe my clutch is off balance.

 

can't say for sure but my 700 EFI vibrates a little too but I think it's kinda normal for a twin to have some vibration. welcome to the forums and hopefully we can all be help to you when you post.

 

Try a new belt, you may have a burnt spot on yours which will make it vibrate...

 

My 700 did that too. I believe its because of polaris's method of rotation on their twin. Their pistons are both up at the same time rather then alternate.

 

actually from what i have read, the unison of the pistons causes smoother running according to balancing of the system....could be wrong, but my '05 700 EFI runs really smooth....

Thanks for the info

I don't believe it is the belt. I have burnt belts beforeon my 500 and when the white stuff come on snowmobiles. usally you feel those at any RPM. but I will look.

the twin is a smooth running machine when I first bought it.

The water pump began to leak so the dealer fixed the problem inner seal leaking ever since then i have noticed a Vibration.

 

I agree the 700 is a smooth running machine. I think the vibration is caused when you lightly hit the throttle and maybe creep forward. I have had people press the throttle very slightly and stop and ask if it was supposed to vibrate like that. I never really noticed it a whole lot during normal riding.

 

Robdog,
I would definetly check your belt, I burnt mine on my 700efi and it started out as a vibration as well that seemed to carry through the whole machine,also if you let the belt come apart chances are it will break the cover, one thread of the belt was starting to make its way through mine right where the cooling intake is on the cover.
