09 Nytro XTX, Slydog trail skis, 6 inch shaper bars - significant darting.
Got new ski spindle bushings and installed Snowtrackers last week and went for a ride yesterday - NO DARTING AT ALL!!! Could go 50-60mph and hold the handlebars with one hand. I did follow the ST's instructions for the set up - take away all front spring preload and tighten up the center shock., and set the toe to 0. What a royal pain in the #*$&@ to get to the inner lock nuts on the steering arm, wow. Took hours to align the skis - any tips for next time?
This setup definitely cured the darting but there was not enough bite in the skis. I will have to loosen up the centre spring some. The instructions say to tighten up the center spring at about 75% - whatever that means, I set it up to be close to the hard setting as found in the owners manual, but this was way too much.
Additionally they don't sell the STs for SlyDog skis, but the ones for c&a skis will work. Thanks to "DGZRT" here for the tips on installing these. (When drilling holes to fit the STs use as small a whole as you can, so you don't break the keel in half)
Disclaimer - My toe previously was way out of wack, the new bushings didn't seem to help that much, still some left to right play in the skis, and the old shapers have seen better days. So perhaps if i remedied these things the darting would have been much better, but as it stands the st's are a 10/10!
