Scuse for my english...I do my best.
Someone had vibrations problems under your Apex 2010??? After some reflextions and brainstorming, we think that the sprocket extern are in problems...they create vibrations, lost of power over 60mph and poor acceleration over 8000RPM.
Top speed....150KM/h!!!!
Clutch are ok.....everything is ok!
Sprocket extern and intern are also on Nytro 2010.
My dealer and I have maybe a solution....with Yamaha Canada too.

Sorry but i need more information?FireStone said:
Salut,
Keep me informed. I heard that complaint. I am changing the track on my new sled as I do every year. I did not test it yet. Should change these sprockets for internal only? Is it possible with the 2010 shaft?
Thanks

I put this question here to have another idea with different people...
Bye bye

Perhaps this would explain the lack of top end on my 2010 Vector. It has good acceleration and seems to peak at 90 mph or about 145 kph. I had a 2008 Vector that could out do the the top end speed of my 2010.
Yamaha claimed that the 2010 would outdo the previous vector by 7 mph. Was that with the previous drive train? Who knows as some of the early reports was with the new engine in the 2009 drive train.
You report that the 2010 Apex has a top speed of only 150 kph - the only thing common with the Vector is the drive train (involute/convolute sprockets)
I also notice excessive noise between 30-40 mph coming from the track - sprocket area. After that the wind noise drowns out that noise.
Lets hear from more people on your 2010 Yamaha
One other thing I thought of is that I'm going by the speedo what if Yamaha made the speedometer accurate. Can anyone verify their speed with a gps or radar gun.

The noise at 30-40Mph is made my the track and sprocket cuz the track run too (smooth-soft) and the track do (oscillations) and the convolute sprocket can't enter correctly in the track holes....like 2 gears of different size together. The sprocket fight with the track and you loose power to pass over 90Mph.
In 2005, BRP wanted put this kind of sprocket on MachZ, but they forgot this idea . Top speed was so bad and there was vibrations.
So Yamaha takes an old idea.......bad decision I guess!
The first solution will be take off the sprocket extern and put the same sprocket intern with a little fit. We will return with the same kind like the Apex 2009-. And will keep the 30mm shaft......2009- have 27mm.....

FireStone did you say you contacted Yamaha Canada
and did you get a response from them?
Where or whom were you in contact with?
The reason I'm asking is I sent an e-mail to Yamaha
Customer Relations Canada. I don't know if that will get me a response I want. I feel it should be dealt with at their Engineering level.
Maybe if more people complain something maybe done.
I'm very surprised that more people haven't chimmed in on this or are we the only ones that have opened up our sled and asked what happened to the top end speed.

Just like to report that things have gotten better with more time on the sled and setting the track looser
then spec calls for. I got 100 mph out of it today on speedometer.
There is a drone between 30 and 40 mph and I guess
that is the nature of the sled.

If I understand, You run the track looser than the Yam spec???
The kind of rattle with the track is not normal.
The dealer adjust my track harder like the 2009- and I win 12km/h....so 163km/h in normal condition. I run with Green-grn-grn spring. My Rpm is supposed to go at 10900-11000.
And I have also the 24th gear.
After the Hollydays. We will do other setup and we will correct the big problem.
To be continued......
Maybe a new track 1"....

So my understanding is you have a 2010 Apex not sure you said if is a LTX ?
Mine is a 2010 Vector Ltx I cannot find the 2010 Apex parts list but I assume the skid and drive train are the same, as well as the track at inch and a quarter.
Are you saying with your track fiddle tight you no longer get that drone in the 30 mph range?
I had that drone even with the track according to yamaha's spec
You mentioned you were going to take the extroverts off but the shaft size being bigger you couldn't find involute to fit. My idea is to use the same part number as the involutes that they are already using in the middle of the shaft. I know there will be extra cogs on one side but that shouldn't matter or you cut that side off.
Let me know what works for you
Thanks

Just wondering if the guys in this thread have any more info on this. Picked up my 2010 Apex LTX GT today; went for short ride and did notice some wierd noise underneath at about 40mph. Have not opened it up yet but have heard some other comments about this same thing and a lousy top end.

What I'm noticing now is that the front slide protector
is getting chewed up by the track. Of all the different sleds I have had including my 2008 Vector Ltx I never ever had this problem. This has to be a design problem that never had sufficient testing in all snow conditions.
I have been sledding on lakes with about 10 inches of soft snow so there is more then ample lubrication.
I have tightened my track to spec 30-35 mm with 22lbs pull and will be watching closely. Looks like in loose snow conditions the track gets pushed towards the slide rail and chews up the front of the rail slide protector.
It appears with the new drive and rail design the track can not be run loose

Thanks for the comments; have to watch for this on mine. Other wierd thing I notice is the speedo is out the opposite way that it usually is. On my GPS and my buddies GPS at a GPS speed of 70 Kil. per hr. the speedo was reading 64 KPH>

If you ride in a lot of deep powder with a MONO you MUST shorten your LIMITER STRAP cuz the front rails sharp approach angle will STAB clips and tarck and will chew you rail caps and pull track clips off...check to see if you havn't lost any clips.Your also right on the LOOSE track in deeper snow it'll tend to STAB your rail caps.You just can't win, you either set-up for TRAIL riding on BACK COUNTRY...
