I have an 07 Phazer FX. I have installed about an 1/4 inch plastic shim into the rear of the ski. I then rode the sled and this helped reduce the darting but darting was still there. I then rotated the rubber ski block around, since guys over in the Nytro section have been having good luck doing this. I then test road and this has also has helped reduce the darting. I would say that these two mods decreased the darting about 70% or so. I am finally getting my sled to handle the way I want it to. I lowered the limiter strap two holes, this greatly helped reduce the inside ski lift, although I cant pop the skis off the ground anymore while taking off, and I also reduce the front skis preload as much as I could. I now still have two things I don't care for though. One is when I am driving down trails, mostly railoroad grades or anywhere where I get alot of speed going, I will then let of the gas and the sled then will start swerving all over the place to the point where I am slightly worried that if the conditions are right I will start to roll the sled over. Anybody else get this feeling? Also right now the Phazer steers heavier than my Apex with C&A skis. Up on a stand it steers fine, I know I lowered the limiter straps with adds pressure, but it steered heavy before I did that as well. I feel that shimming the skis may have added to it slightly, but I would rather have less darting and heavier steering than alot of darting. Also I should mention that lately with the steering very heavy the temps out side have been about -10 while riding. Any suggestions for my problems?
I have had alot of problems with darting and the sled seemed to be very tippy through the turns. I to have lowered the limiter strap and a couple of people suggested dualies for the fornt skis. I was soing to order a set, but was not sure which to purchase, because of the 72 studs on the back. Any body else running dualies and has this solved the porblem?

The only cure for the wild swerving I found was doolys. Everyone told me to do the above, but only the doolys solved the darting while keeping the steering light. With the added bonus of stopping the off throttle swerve......
what size dualies did you put on? And do you have the track studded?

Dual 6" with stock track. Guys who get dual 4's seem to find their sleds push a little in the corners.....Good luck.

I agree that the doolys completely eliminate any darting.

I ordered a set of Bergstroms and they came with a few goodies.
Including shims for under the rubber, and ski savers
which also work as shims.
While I don't think I've ever noticed darting, its definitely not
there now.
I also added Scotts "contours" to the mountain ski.
You'll have to ask him about them, I did it just to see
how they worked, and I have no real issues with them
makes the ski more of a tri-hull than a deep keel.

I shimmed the skis and put on 4" dual carbides and it was night and day. I might try 6" next but tracks and turns way better. The stock carbides are junk!

i put on 4" dual carbides and it was a lot better. now i just have to tighten my limiter strap, rebuild my front shocks, and cover the hole and tis will turn it into the best sled ever.

jeff dont waste you money on dually's. if anything go with bergstroms triple point carbides. but really the best and cheapest method is to shim the ski bumpers.

Gerard 143 thanks for the reply. Unfortunately now the darting and heaving steering is the least of my worries. 2 weekends ago, I had the link break with about 2200 miles on the sled or so. When the link broke we still had to drive about 25 miles to get back and the track got torn up supposedly, thats what the dealer said. The next weekend my father and I picked the sled up and it was like new, got all the new rear suspension parts installed, new track, hyfax, wheels, cold start update all covered under warranty. The track was studded and yamaha is not able to replace the studs under warranty which kind of sucks, but I understand why, other than that I am very happy. My father and I starting riding the same day, got about 40 miles and he got pulled over for blowing a stop sign on the sled. About 1 minute and 270$ later we notice a strange noise coming from the primary clutch area. We take off the cover and see if we can diagnose the problem even though we know nothing about fixing snowmobile clutches and engine parts. We thought the sound was just some loose bolts on the primary so we tried to tighten them, but the with the tools we have that was just not going to happen. We decide to turn around and about 3 miles down the trail my dad said the Engine just shut off and the engine light came on. He said he could hear all foreign noises just a bit before this happened. Anyway we had to tow the sled 35 miles back to the dealer. Now when we turn the key the primary spins but not the you can tell the engine does not turn over at all. So for all we know now the engine could be blown, or the starter shot, I have no clue. Luckily everything should and will be covered under warranty.

Has anyone ever tried the Snow Tracker outfit referred to on the Supertrax website? Supposed to prevent darting and ski lift.

ya i wouldnt worry about warranty coverage. if the primary is spinning but not that motor what i would guess is that the starter gear is just spinning on the crankshaft.
from what i can see on the parts microfiche online on yamaha's site the starter gear is just pressed onto the shaft. however, unless the clutch is spinning on the shaft too which seems odd (although u could verify this easily by cranking it over and looking at the shaft to see if that is actually spinning with the primary clutch) then my next guess would be the crankshaft is broken and the starter gear and clutch are spinning but the rest of the crankshaft isnt because it broke. thing is the starter gear should be pressed onto the shaft behind the clutch, but not actually bolted to the primary clutch as far as i know so if both are spinning and the motor definately is not turning over then broken crankshaft it is.
i'm gonna go look at my sled now, but i believe the starter gear is merely pressed on behind the primary not actually bolted. if i'm correct i won't update this post.
lemme know what you find out.
UPDATE: good news brother. which makes sense anyways due to balancing of the crankshaft, but the starter gear is on the opposite side of the clutch, so if your cranking the motor over and the clutch is turning as well the crankshaft is not broken and the motor is indeed turning over.

far as those snow trackers go, so far the best reviews i've read come from bergstroms triple point carbides and simply shimming the ski bumper.
