P500 Twitchy on pavement

[70Bones]

Sorry if this is a stupid question; I haven't near the SxS experience of most of you. Why is no one suggesting reinstalling the sway bar that was removed? After all, isn't its purpose to counter the problem of side-to-side rocking?

Again, sorry if the answer is obvious to all but me. I'll just return to the children's table.

That's a good question to ask! I've had a similar experience as JSPEED when my tire pressures were low, with and without the sway bar, so I don't think that is the problem. If he found it leaning too much on turns, at speed, then the sway bar might be the culprit. Just my thoughts...

FWIW, I've been running 9 psi in my BH's since the day I put them on, seems to be a happy medium and work well for all conditions.

I normally run 8 to 9 on my Blackwater Evo's - However, when we did the Mac Bridge crossing this past fall, I bumped pressure to 14 PSI specifically because of the pavement and that worked great.

Is your knees hitting your chin yet at the kindergarten table?

On the 500 most of us remove the sway bar to allow the most travel in the suspension. The ride is certainly improved for the trade-off of stability!

I was thinking the same thing but I agree with all the other comments about adding some air pressure. I still have my sway bar hooked up as I drive a lot on hard roads. I have fake big horns (bias ply) and I run at 8psi. Even with the sway bar connected it will wiggle every now and then especially in a curve.

Not sure if anyone has mentioned this or not but adding a little toe in will make it more stable. If it’s toe out it would make the steering a little more sensitive and with a short wheel base and narrow width that may be felt as twitches. Does anyone know what the toe should be?

4lbs all way around

What kind of tires?? I recently rode with a guy the day he brought his P1000-5 LE home. He ordered it with s 3” lift and some BA tires (I forget what they are) and after an hour ride, he was ready to take it back, very pissed off. He traded in a RZR on it. He said the ride sucked. We checked his air pressure, he had 15lbs all the way around and the tires said 6 PSI max!! The side wall on his tires is so stout, they stand up empty. With 4 PSI he’s now happy and not threatening to return it anymore.

That’s for darn sure if it’s toe out....

Agreed.

I'm running 8-9 psi on my 26" Roctanes on the original rims. It runs great on pavement. Most of my riding is on gravel and we squeeze between alot of trees on the tighter trails. I can't imagine going 4 psi even on my quad. As soon as I had the Roctanes, all that wallow on cornering disappeared.

Low air usually feels like your riding a big girl on waves, twitchy is usually alignment, mostly toe. Get the alignment correct while running higher pressures (depending on tire and weight 14 psi +) and then lower psi to suit comfort, responsiveness in steering higher speed and tire bulge when flexed.

I’m running 27x9-14 Terrabites and they have a oval to them. The tread isn’t flat and I’m thinking that maybe that’s part of my issue as well as low pesssure! Getting a air pump today and trying them to see the difference

Does anyone notice their P5 being twitchy if driving on pavement? Sway bar is off and I get a lot of twitchy side to side rocking when driving. Sway bar is removed. 1.5" spacers on rear only. using 12" aftermarket 5+2 rims with low air pressure. I'm thinking that this maybe the reason as my old 14" rims on the old P5 didn't do this hardly at all. I wonder if its in the rim size, air pressure or something else? I wonder if front 1" spacers would help?? thoughts???

My question is...what is this "pavement" you speak of?

He had 20+ in one of them. Lol

Evo’s Have an oval profile as well. I had a 52 Willy’s M-38 Jeep with military NDT (non directional tread) tires and unless fully inflated it was squirrely as all get out on pavement, which is why I ran my Evo’s at 14psi on the bridge crossing to ride the center rib per say.
If I’m only going a short distance on pavement and mostly off road I put up with the twitchy steering, however I also carry a portable pump to adjust pressure if needed. Always a trade off, on and off road.
I do think the EPS helps on pavement, still twitchy but somewhat more behaved.

 

[GRANITE]

I bumped up to 8psi and all the twitchy is about gone! Some still there but huge improvement! Thanks for everyone’s input

I bought a new gauge today to replace my very old one. It reads abou one PSI higher, so I may be running up to 7 psi, but usually stay around 5.5 -6

What did you get?
I own a couple of ACCUTIRE digital gauges.(I lost the first one in the clutter of my tool box for a few years) One has a range of 0 to 99 psi and the other goes to 150. They were around $12 and appear to be accurate, at least they both read the same. I got them because they were highly rated by Consumers Reports.

Alignment?

I agree that its the alignment. I had the same issue when mine was new. In a curve it would lean inward and then violently go outward. Scared my wife. I thought that is just the way they handled until one of my front tires was nearly worn out at 200 miles. I carried it to a local alignment shop and had it checked. Toe-in on one side was out by 1 inch and the other side was out by 2 inches. Handles great now. My dealer says this is not covered by warranty. I could see this causing an accident and a potential law suit. Can’t believe Honda ships them that way.
