sled darting

[myrodman]

I have a 06 attak with Yamaha tuner skis running 6 in carbides on the outside and 4 in on the inside The sled darts really bad I checked the toe and it's set at about 5/16 toe out Is this toe setting correct or does anyone have any other ideas? thanks

Is the sled studded? Did set your sit in, measure spring before you sit on sled and have a friend measure while you sit on sled. Think man calls out for 40mm to 50mm difference. What were conditions? What is your transfer at? I run my transfer at max while slow trail cruising riding but when I ride with a different group I set transfer to min for more of a gas and go riding style. When transfer is at min you corner flatter and faster but sled will dart somewhat more setup like this. I have beg triple pts on my sled its extended to a 136 with a ice ripper track. For me if darting gets bad I increase the transfer its all comes down to personal preference. Are your skis shimmed to lay flat?

The sled is studded and I did not set in it while measuring the toe It darts at pretty much all conditions I have never checked transfer but can look in the manual to do this Can I ask what you mean by shimming the front skis to lay flat? Thanks

Snow trackers eliminated 100% of my darting.

This article is worth a read at least. "Some riders who bought these skis started out with way too much carbide, or way too aggressive in their runner combination selection." https://www.snowtechmagazine.com/yamaha-dual-keel-dual-runner-skis/

If you shim and align your ski's and they still Dart . Check your front end bushings by getting the front of the sled off the ground and grabbing the upper "A" arm back by the bulk head . If there is movement the bushings are shot and should be replaced.

Different year Apex here, but first year with tuners for me, running 6+4 with zero toe, no darting or hunting, so far impressed.
As mentioned above, check for loose bushings in A-arms and spindles.
When setting toe, make sure you bungee the skis at the front to account for any toe-in slack, and when checking toe, sled should be on the ground not in the air.
Cheers.

Ditto. Got em on pilot skis and have gotten rid of 95% of darting. Love it.
