RZR wheelies while wheels are still on the ground.

If I floor my RZR the front end lifts up about five inches but the wheels never leave the ground as I slowly back off on the throttle the front end slowly comes down. I have all four shock on the lowest setting trying to cure this but no luck. also as the rzr lifts the steering wheel moves back and forth and the front wheels are toed way in and when I slow down the wheel whips back and forth again until the rzr lowers back down then it drives normal again. I had a friend watch down the street and he says
when the front of the rzr raises up the two front wheels actually go closer together and toe in. the A arms drop all the way down as if you lifted the center of the Rzr with a jack as far as you can without lifting the wheel off.
Scary Situation. any ideas. motor is stock. but somthing in front suspension seem changed.

Sounds the weight is transfering to the rear.
Try increasing the preload on the rear shocks, that should help keep the front end down. :)

I'm not sure I understand what the problem is... any vehicle is going to raise the front end under acceleration. The more suspension travel and/or power it has, the more this is going to happen. It's perfectly normal. The steering is probably shaking from being in 4wd and the front tires trying to get traction without mush weight on them.

thanks moosehumper. I just tried cranking my rear shocks to their hightest setting and the front shocks on their lowest but the front
still raises up about five inches and the wheel still stay on the ground.
I had my wive drive it and give it quarter throttle it still does it .as you
let off the throttle it still rides about five inches too high until you are going about 15 mph is slowly drops back down to normal height. its somthing to do with the front suspension, scary as hell to drive it. it is in two wheel drive too. so that's not the answer either.

front end

Check your tow....If the front wheels are toed in too much,the wheels are constantly trying to go to the center of the machine which would in effect put force on the suspension trying to pick it up....This force combined with the force of the engine picking up on it could be your problem....Too much tow in can make it feel "darty" in the steering as well.....

thanks for your help guys I will tinker with it again when I get home tonight. some good idea' s to try. I will let you know what i find.
If you have the rear preload set at full stiff and the front at full soft, its going to drive really strange. Always keep them close to the same setting. Set the front at full stiff and the rear at full or 1 click from full stiff and it should be perfect. From the factory the set preload is way too mushy, but they had to do this to get a plush ride. This is also one reason the buy a shackle lift, it take that mushiness out of it and gives you more ground clearance.

The front of the machine should lift some. It sounds like yours is excessive. Have you done any mods to your machine? I actually have mine set up to lift the front. The rear ride height of the chassis is 3/4 of an inch lower than the front so that it will transfer wieght to the rear and handle the whoops better. It make driving it over bumps a lot easier.
What is your tire pressure front and rear? What type of tires and rims are you running, or is the machine all stock? This may help me lend some insight into what you have going on. Do you have any wieght in the rear of the machine? Let me know and I'll see if I can help.

Well, I tried more toe out, still does it. tried all different shock adjustments
no luck. my engine is stock. Jagged X was kind enough to loan me a pair of stock shocks, put them on and the same thing. I have the polaris brand
of wheels and goodyear rawhides 14 inch wheels and 26 inch tires. still
the front of the razor raises up 5 to six inches and the wheels go toe in which makes it hard to steer, darting around and when you coast it still is up high and when you finally slow down around fifteen and step on the brakes if drops quickly down and stays down and the toe is out about a
half inch and if you stay slow it drives like normal. but again even if you give half throttle the front end raises up about five or six inches and the front wheels actually go in toward each other about four inches and the tires go toe again. driving me crazy. tire pressure is 8 pounds

disconnect one of the plug wires.. that'll fix it.. :)
Oh man, you just killed me... I laughed so hard my eyes are watering.... :lol:

Back to topic... is this on dirt on asphalt/concrete? Mine certainly lurches backwards much more on a paved surface than it does in dirt. But, the shimmy in the steering wheel is odd.

Perhaps a silly question, but have you checked and/or retorqued the bolts in the front end?

sounds like somthing is broke, and comes out of place when you are on the gas. Jack up the front, and start grabbing the tires, and see if you can get them to move around. A-arm bolt, or somthing. That is way too much movement for somthing not to be broke.

The sensation you are encountering in the steering is caused by the transition from toe-out to toe-in and vice-versa. That action is called"Bumpsteer". Take a Ford truck with Twin I beams and drive through a deep dip or over a hump like railroad tracks, as the suspension collapes or extends the toe-in/toe-out changes. You actually turn the steering wheel a little to keep it going perfectly straight or it makes a veer. Bumpsteer is caused by incorrect steering box location or poor geometry(a-arms length vs. tierod length).

I would guess that most of the people that responded to you are correct in part.
1) extreme toe-in toe-out causing shimmy
2) weak rear springs allowing excessive weight tranfer
3) accelerating on conc/asphalt giving excessive grip = weight transfer
4) front shocks probably shot giving little to no rebound control which would slow the rise of the front end
5) My guess is you have added either high weight or rear weight creating way too much weight transfer. You would need heavier rear springs.

All these are normal when your suspension is shot!

Oh yeah.....you have both spark plug caps on! Good one Marty!!!LOL

RZR front suspension problem has been resolved. I brought my nightmare driving RZR down to Jagged X for repair after myself and several others tried everything trying to find out why my RZR was so hard to drive. Apparently when I had iron city polaris repair my front diff.
they installed my front tie rods upside down, they put them in from the top. Brandon at Jagged X watched me try to drive my RZR with the front end wheelies and toe in going in and out. he then looked underneath and came up with a big smile on his face and said your tie rods are installed wrong. So I left with them to fix it. picked it up a little later and she drives like a brand new RZR. No one is going to touch my RZR from now on
except for Jagged X these guys are great. My thanks T o Justin, Brandon,
and Adam. well we have a small group heading for the dunes (Buttercup)this weekend for one last ride before the heat wave. Just look for the Orange fullbore bodied RZR. Shredder :D

Yes I saw red, especially when they(iron city) charged me $730.00 for the front diff repair. which they said was Polaris's fault since the wire that was pinched causing the problem was done at the factory. but I still had to pay
since my six month warrenty was up.

How would that Orange Body look with these? http://www.vogtland-na.com/racingsprings.asp?type=250
