Darting issue 98% fixed!!!

[bagadonitz]

Can someone verify which way the rubber should be pointing?

The rubber has two different sides. One the top of it has notches, the other it doesn't. After mine were turned around, the notches were at the front of the skis and the ski tips were up.

Reason I ask is I was at my dealer yesterday and this is the way it was on the RTX on the floor? So I'm wondering what way I have it.

A picture of these shims would be great.

You got it right bagadonitz. Your dealer probably installed their's "incorrectly" (even though it actually works), or they knew they should be installed that way to prevent darting, they're probably reading on here more than you saying As long as your skis are pointing up, you're good to go

Berstroms here too.

bagadonitz, Mine were that way from the dealer as well. I have been scratching my head reading the posts on darting and flipping the rubbers. I picked up mine about a month ago so I don't know how the dealer knew to turn them. They do look like they want to go in with the thick part of the rubber to the back.

That's my issue. When I turned them so that the notched end in was in front, tipping the skis up, it seemed to me that was the way they should be anyways.

I did mention to my parts guy at the dealer, who also has an RTX who was asking me about handling, that he should turn his around. Perhaps he did and he told the service department to start setting them up that way. Or maybe that is the way it should be anyways.

As with most things, a picture is worth 978 words (inflation erroded the other 22). The arrow points to the front of the ski:

Jacked the front of the sled up off the floor and surprise!! one ski dead level with the floor the other tipped front of ski down about 3 inches. Sled has never hit hard or crashed yet. Turned the rubber pcs around on the tipped ski at least both are even now.

So you have one pointing one way, and one pointing another?

Guys,
You should have the fatter part of the ski rubber towards the rear of the ski. The reson for this is to help bring the front of the ski off the ground. If you have flipped the rubbers and the skis are still flat, you need to add a 1/4 shim under the rear of the spring rubber to lift the front of the ski more.
When you put your sled on a flat concrete surface, you should be able to look at the carbide, and have the front it sitting off the ground. This will eliminate just about all of the darting issues with the stock skis.
The fix worked great on both mine and Tom's sled. Mine still has stock carbides, his has Bergstroms. A longer, more aggressive carbide can make darting worse than a stock carbide on any given ski, so if you have aftermarket carbides, this tip can be even more important!
As far as the SlyDogs, I can't tell you from experience, but if you have a stock ski, this works awesome!!

If you look at the rubbers in the pic they look like they FIT the spindle. If yours were the other way they must have been assembled wrong..? Mine were like the pic when i got the sled..

where did you get the shim at ? can you post a pic of your skis in its new setup

Just curious what holes everyone is using on their front limiter strap with the ski rubbers in this postion?

 

[jojo567]

This is the first Ive heard of this. This really works? So I want the ski's pointing up? If this works it will take away my hanging on for dear life. One more question where do the shims go?

Yes mine were the other way when I got the sled. The ski tips were pointing down when suspended, and I feard I was going to become acquainted with the brush on every run.

I turned them like this, and as you say the first thing I noticed is that it looked like that is the way it should have been. The tips now point up.

I would love a pic of these shims or a description of their dimension and where they go (I imagine under the left side of the rubber in my pic)?

I have the limiter strap on the front only pulled up one set of holes and with the rubber like it is in the picture, the sled wanders a LOT less.

Here is the rubber on my FX Nytro installed and this is the shim that I used from Bergstrom. I just did the Phazer and did not have to flip it around to get the same affect. I just had to add the shim under the rear of the rubber. Both the Phazer and Nytro add it to the side with no holes in the rubber when its flipped upside down. Install shim with 1 S.S. screw in the center of the shim to hold the shim in place.

BTW, I will be doing more trail testing on this on the weekend.

 

[bagadonitz]

How thick is this shim? 1/4?

We have a trip planed for the weekend and I have some plastic kicking around. I'm going to give this shimming a shot as I found it was still dancing around a little.
