Hi guys..just bought a 2006 500 auto and have 5 miles on it and I'm getting a real bad vibration type noise, its very hard to tell where its coming from maybe belt case area. does not make the sound when idleing, seems to start around 2000-2000 RPMs.and quits around 3000rpms? doesnt sound good though. Ive rode the first 5 miles pretty easy never above 1/2 trottle. This quad is replacing a stolen 2005 500 and I never heard this sound when breaking that machine in. any idea's?

 

Got it fella's...the skid plate for the cycle country plow I just installed was putting so much pressure the the footrest bracket that it was making contact with the transmission housing. removed the plate and vibration gone. I knew it had to be something stupid.

 

i just got a 05 500 4x4 at.

i don't hear vibration but i can FEEL IT!!!
it's on the floor board.....i can feel it through my shoes and just tickles sometimes till i reach a certain speed.

 

That vibration is called a "single cylinder 4 stroke engine". Get used to it cause it is there whenever the engine is running.

 

This vibration was not there on my 05 500. when i take the plow mounting plate off the vibration is gone.

 

Not yours, scooters. But remember for something to rattle and make noise, there has to be something causing the movement. That's the one lung 4 stroke motor. If anything is loose or just barely touching they will rattle because single cylinder 4 stroke engines have way to much time between power strokes. Once revs get high enough the time between power stroke shortens and the vibration seems to disappear. It doesn't, it just happens so fast you don't feel the seperate pulses anymore.

 

thanks for your responces

i used to have the 02 400 polaris and never felt the vibration in my feet.
i don't think it's the single cyl 4 strokes. i drove many dif kinds and never felt that.

but who knows

 

Was the engine bolted to the frame without mounts on the Polaris? Is your vibration only when moving or anytime engine is running?

 

i did forget to mention...

it is the 05 AC 500 4X4 AUTOMATIC THAQT IS CAUSING ALL THIS.

THE POLARIS AND OTHER MACHINES NEVER HAD THIS FEELING IN THE FEET.

 

I was asking about the Cat. The only Polaries' I am familiar with are the Sportsman 700 and the Scrambler, so I was asking for info for the comparison.
