This is driving me crazy......dealer could not get it to do it....DUH.......after you ride for about 15-20 mins, there is an annoying vibration/rubbing under my 700, it runs great and after you get it up to 30 plus it doesn't do it as bad, but with steady throttle at slow speeds say 5-15 mph there is a drivetrain vibration you can feel through the seat and mainly the floorboards, also you can almost hear a "wooo wooo" sound with it....like I said i've heard and felt this for about 125 miles now an it isn't getting any better, it feels like its in the tranny or driveshaft.....I have checked for loose motor mount bolts and they seem tight but I don't know....anyone out there had this problem....I have heard that the Artic cat 650's have been having trouble with the trans in them so maybe it is related........HELP

 

Sounds like a bent drive shaft. That would explain why it gets better as it spins faster.

 

I had a problem like that also and it turned out to be the bushings in the driven clutch. I had a machine shop mill them out and put in oil lite brass, so if you have some miles on it or you ride in dusty or muddy condisons this might be the problem.

 

I seen thins on bent axles too on the left side next to the gas tank with ovesize tires only. Also check your airbreather on your clutch cover make sure it's clear. Easy way is to rev it in neutral and listen.

 

Took it back to the dealer this afternoon, Service mang. said he would check clutches and belt, then u-joint and rear output shaft, He said he would split it and go into the tranny if they couldn't find anything wrong......2 year extended warranty thank god.......I'll post back and tell everyone what it was......

 

UPDATE::::: Well it turns out is was the motor mount bolts were loose, and one of the rubber gromet's under the skidplate was missing also, rode it just a bit after I picked it up and it seem's to be OK, service manager said the rear one was loose enough to where it was black colored where it was working up and down, also said that we all need to check these out at first service time, all the fastners, bolts, and such........charged me $10.00 bucks to do all they did...I have a GREAT DEALER and SERVICE DEPT, they really take care of you after the sale...........
