Regarding the discussion between Duely's vs. Triple Points, I have this experience with my two '09's. I finally took the stock carbides off the Vector after 700 or so miles, and found them to be worn raw, with a signfiicant wear mark, concaved toward the center, right where the pivot point is. Bergstrom sent me shims for the Vector so I had it shimmed, and added the 6" Shaper Bars. The thing corners about perfectly and night and day difference betweeen stock carbides and Shaper bars.
Now the interesting thing is, the Apex is also shimmed, has ski-savers and 8" Bergstrom triple points, and it clearly feels light on the front end, like it has less ski-pressure than it needs. It corners O.K., and does not dart, but it doesn't feel as precise in cornering as the Vector does. I think this is possibily because I have my rear shock set more toward the firm side, I don't recall without looking at my notes, how many turn I went, but about 2 mm or less is what I think. I did not want bottoming, at all costs, I wanted to limit possibility of damage to the rear exchanger, even though I have it protected with my own mod, I have pretty aggressive (1.4" Extreme Max - 162) studding, all down the middle. I've heard you can still touch with a hard bottom, even with protectors in place. Dealer told me as you go toward the firm side on the shock preload, you will start to miminize ski-pressure, and sacrifice some bite/control. After I rode it a bit, I understood what he meant. It's still good enough that kid or wife can ride it and feel in control, but it doesn't feel to have the front bite of the Vector.

Fusion:I bottomed my 07 Attack once in over 6000 miles & you are much lighter than me. I'm turned to stiffest spec. PIA but try & to soften mono spring a bit. Also know when I move up on seat Attack corners really well with 8" triple points. Stiffend front shock clickers compression & rebound & made rear mono stiffer & carbides bit better too. Go figure stiffer rear? Seems you change this & that & in turn changes something else. Glad I have the ability to have these adjustments.

What about the limiter strap? Have you adjusted that taking pressure off ski's? Just a thought.
I had both, '06 Apex and '07 Attak EC Monoshocks re-valved by pioneer performance last summer. Huge difference on the bottoming issue. I would bottom out at the higher speeds when I hit a dip in the trail, especially after coming down a steep hill with a dip on the bottom. I ride trail 5 north from Iron Mountain a lot and the section of trail along the power lines really test the rear shock. Since this was done, I haven't had any problems. the Apex actually got a new stiffer spring to bring it in line with later models specs.

Its a done deal Went to Highlands Yamaha in IL and bought a new 09 apex ltx Gt. In the traditional blue and white. Man that thing looks sweet. Must admit no comperasin as far as fit and finish from my 05 sabercat.I did junk the carbides and put on some duelies Cant wait to pu and head north on Friday.Thanks to everyone for their advice and if the info i got is true I will be happy with this sled for along time.

Saber - congrats, you will really like the sled, I have no doubt. You will have some "getting used to" coming from your current ride, but I doubt you'll find much to complain about. But it will be different. Most of what people were telling me to watch for I never had a problem with, but it could be my setup was that good. I never bottoming the thing once all year, but I rode pretty good trail conditions in the time I was up there. You will really like the EC Ohlins, it really is cool to be able to change the preload at the click of a switch, based on conditions.
Season was way, way too short for me. I wanted one more trip, but doubt that's going to happen now. Mid 40's in northern WI this weekend.

I'll wait to tweak a bit over the summer. I might soften the rear preload a 1/2 turn or so, given I had no bottoming problems, I'm probably not utilizing full travel of the rear suspension. But still, really no complaints, just different ride than the Vector.
On another subject, what the heck happened with this weather up in your area this year? The last month has been the pits. No snow and too warm - bad combination.
Congrats
Congrats you will luv the sled & the broad power of the 4s Yam 150. If you have questions just ask lots of Apex riders on JD.

Yep Bad Year
I know it has been a tuff year. Your 2nd home .... riding trails from ER & St Germain have been the worst trails of Vilas County since the ER Derby & 1st thaw. That thaw & traffic combo killed your area. Phelps had a lot more snow so Phelps trails were pretty good but 6W joining up with Lando trails has been beat all season too. The north escape route FRs from Phelps were fried this year due to logging so forced more traffic back thru Lando so more stress on 6W. 1 bright spot this year has been Watersmeet trails so rode a lot thru there & North in UP. El Nino is causing warm temps & very bright sunny days so WI trails are done or soon doomed to mud. My problem is I either rode 175-300 cross country UP miles or I didn't ride. I really missed the 75-125 mile screw around local rides as trails to other areas from Phelps sucked but got on the Kimball to 3 lakes 1 or 2x in early Jan & that was fun. Tough year felt trapped in Phelps trail system going east, west or south was scrappy within 25-30 miles. Still hoping for huge March dump but not looking good now. Good thing you had that rear heat exchanger on your Apex LTXGT riding thru ER bare trails.

Congrats on your new sled. I remember in the mid 80s I bought a new sled in mid March (when we rode Yamahas.) I couldnt wait till the next season to ride it. So I woke up early on a sat. Trailered up to where there was snow, rode a few hours, then trailered home the same day. I still remember every minute of that ride. Nothing smells like a new sled baking in the mid March sun.
for darting..here is cheapest fix, no shimming, use stock carbide, stock ski....it flat out WORKS!
read all about it here:

buy it here: go to ebay and search 'dartless'
just so you know, i do not know the guy who sells these...never met him. i'm not a 'shill'. just 'took a chance' and am VERY pleased. especially for those on a budget. here is a pic of me. you can see them on the ski!

Looks like i can fabricate them I will keep it in mind but for right now the dealer talked me into slim duelies they seem to work.if not i will give those a shot.I am praying we get one more storm because i am itching to ride again but if not its going to be a long summer.
