Undecided...thanks for the advice and ideas. I'm actually in the town of Vernon - Waukesha Cty., WI. Lots of snow right now, with more on the way, but I don't ride down here. I ride Eagle River, Conover, Boulder Jct, ect Vilas Cty, Oneida Cty, and Iron Cty WI - mostly.
Yes - dealer assures me track tension is checked at the time of setup. I asked him about that today. I wouldn't think I have to mess with that right now. I need time for the track to stretch with the studs, and I've heard bad things about loose tracks with studs.
The only thing that worries me a bit tonight is the stud length. The dealer assured me Extreme Max, 1.4", with Round Aluminum backers, and big nuts was the ticket. The penetration over the lug seemed reasonable to me, not excessive. I kept them all in the middle - 120 total, 3/2/3/2. I used a Woody's template pattern - recommended by the dealer. When installing I was thinking how little clearance there is in the tunnel, with that bracketing for the muffler.
Tonight I'm stressing about whether a stud got caught on one of those brackets in full squat, coming up the ramp? Doesn't seem likely, but my brain box is working overtime on this one. I'm pretty sure the dealer knows their stuff, and wouldn't recommend a stud that was damaging or too long, but one never knows these days. This is a brand new sled, so I would assume they looked at the clutch during setup? But I will look at it this week when I get up north.

We moved up here from Tichigan Lake. I was born and raised in the burbs of Milwaukee.
I'm running 144 Woody's Signature Series studs. 1.325 is the length and should be the same for your sled. I doubt that .075" is going to give you any issues. I'm also running big nuts and they are a MUST with long studs.
I'd betcha $20 your track is wayyy too tight. Dealers seem to set them this way. Your track will stretch very very little. I was surprised that my track didn't stretch....mine was studded when the sled was new too.
When are you driving up? PM me with your plans if you want. Maybe we can hook up and I can take a look at your new ride. Don't know where you're going up north, but IMO I'd get some peace of mind b4 you get up there. If u are having a problem, good luck getting it worked on during the Xmas rush.

I'm using the extreme max 1.40", 144 double/single woody's pattern up the center all plastic backers with zero issues. on my 06 nytro. so you should be fine
I am not positive but I thinkl i read somewhere that the 1.40 extremes are the same as the woody's 1.325, they are just measured differently.

I see you have an enclosed trailer. I'm off work on the 26th (might go riding though) and could meet you or you could stop by me. Unload the sled and check it out on the spot.
I PM'd you......
Another thought.............is it POSSIBLE that you have the wrong or defective belt? Wouldn't be the first person to get one.

Next time yer load'n up and have this problem pop the hood open and you'll see the belt is stuffed down in the secondary... I always had this happen with my old sx chassis esp when the belt had a cold set in it...

Tichigan Lake - heck, I go by there every single morning on the way to work, just south of there. You lucky guy - living up there. You got alot of snow down here now, snowing again this morning, and 10 inches more in the next two days. My snowblower is getting a workout.
Thanks to all for the feedback on stud length. After sleeping on it, I'm sure that is not the problem. I looked at the tunnel and the studs and other than concrete dust from the rip I put in the garage floor, no stud scratches. I am with Yamadude on this one. I think it was a cold belt that didn't flex and got stuck down in the secondary going up the ramp. I was probably way, way too cautious with the amount of throttle I gave it, should have maintained more momentum. I ran it on the stand, popped the shroud and side panel and the clutch was sitting up nicely on the secondary like it should. I didn't measure the height over the top of the sheaves though.
Track tension could very well be an issue, and I think I will loosen it a touch. When I was spinning the track by hand to do the studding, I noticed the thing moved very, very hard - very stiff. I looked in the manual and they talk about track deflection, but nothing about tension. Can anyone send me a PDF or brief, to the point description on how to change track tension on this chassis. Polaris was easy, but I have some learning to do with Yamaha obviously.
I will adjust track tension when I put the new belt on up north - probably Friday. One thing I know for sure, I will be pulling it off the trailer by hand, just like the old days, just to be safe.
Undecided, I will PM you over the next few days. (Have to figure out where to access messages and all - haven't done that yet)

Fusion. I had the same problem with a new '09 Vector ER loading it in an enclosed trailer using the ramp. When I was to the point where the skis were in the trailer the thing just wouldn't go, I thought I was hooked up on something, I had to get off the sled then it moved and I have wheels on the skis so I know they were not dragging. It did this twice then the next time I was a little more aggressive and just sort of drove the thing right in and it went OK. I was puzzled just like you why it sort of locked up until I got off the sled, maybe I should go on a diet haha I never thought of the belt sticking in the secondary clutch, could be???

At least now I know it wasn't just me. Thanks for the info Pol600. I sure wish somebody could explain to me what is different about a 4-stroke Yamaha vs. 2-stroke Polaris clutch that causes this.

I almost smoked my belt also when I put dullies on and tried to load the trailer. Yamaies are front heavy and the carbides really dig in. Easy slides or not. Trying to load slowly compounds the problem. I have learned to go up at a bit of a speed now. I agree you really got to be careful you don't hit the ranp with a ski and it doesn't go up.
As for warming up the belt I never do and at times it is minus 20 or 30 celcius. I warm up the engine, spin the track to make sure it is not frozen in and loosen the skis and off I go. I just take it easy for the first few kilometers and then drive at will
The only other reason I can think of for snoking is if something was on the clutch faces or belt and casing the belt to slip (moisture, oil or a cleaning agent)

I have the same issue with my 07 Rage GT. Bought it brand new last year and I couldn't get it off the trailer or on it unless I got off of it and walked it. It replaced a 94 vmax and I never had issues with that one. Personally I don't think it has anything to do with 4 stroke vs. 2 stroke. I think the dealers prep them with way too much tension on the track. After 500 miles my original slides were half melted. I'm going to try a much looser track this season and see what happens.

And.....what exactly is the benefit of this high tension, highly sprung clutch? Does this enhance performance to some great degree? What is the necessity for a clutch that is so highly sprung that it won't engage on a 30 degree incline?
At least now we are getting somewhere - it's the clutch thats different from Polaris, Ski-Doo and Arctic Cat.
