First Impressions of 2011 MTX

[nitris223]

Just took are sleds out for the first time. New to the 4 stroke Yamaha Nytro. We have 2011 Nytro MTX sleds with the Fox Floats. Both sleds are in stock form . Is there anything I can do with the heavy steering. Whe I am on the gas about 60 mph and going straight everything is fine except for a bit of darting but that I know how to fix. What I don't like is having to muscle it around a corner. I have to litterally slow down to about 10 to 15 mph and push and pull on the bars to make a corner. It is like the ski's are planted hard. Deffinantly no push in the corners. I feel like I am going to twist the bars off.

Only thing I did change on the sled was get rid of the stock riser and install a pivot riser. Front shock pressure is 70 psi and rear skid is 150 and 50 psi. Stock mtn ski's and 4 inch carbide. Ant tips to make the front end feel and steer lighter. I would sooner have some push in the corners then have to fight it like today. 60 mile ride and my arms are killing me right now.


Other then that love the bottom end on these Nytro's, ride is so much better then my 2005 RMK.

If steering is heavy, try to increase the pressure in the center shock. This will take some weight off the skis. The stock air pressure is 50 psi, try 60 or even 70 psi. When adjusting air pressure, make sure your skid is raised off the floor. Air pressure is supposed to be adjusted with suspension topped out.

If this does not help, or if the effect is too small, you can also try to fiddle with the front shock pressure. Also, make sure your rear skid to drop bracket mount sits in the upper hole.

Kind of funny. Several threads in the last couple of days talk about too much ski pressure. I can't really remember I had the same feeling...? If anything, I felt the center shock to be hard and harsh, but I can't remember anything about heavy steering...?

You can try to let out the limit strap on the skid as well one hole. if the sled is used but new to you, some people tighten the limit strap one of two holes to get better deep snow performance but by doing that you will get a lot of ski pressure on the trail.
Just remember though the majority of the front end weight of the 4-stroke nytro is directly over the skies so you will never truely get light steering on one of thses sleds.

I believe the limiter strap is all the way out. . More pressure in the front shocks , wouldn't that make for more ski pressure. I have zip ties on there now and it looks like I have about 3 " left of travel. Never let all the air out to see where it actually ends. Just guessing.

I am thinking it might have more to do with the pivot riser being straight up and not angles back. Goung to try a few things next time out. Going to make a set of dual runners, , shim the ski rubbers and also play with the angle of the risers.

Nitris:

I don't know your weight but 70/140 in the skid is a good place to start as mentioned in earlier posts. Also, I would REDUCE air pressure in the ski floats which should also have the effect of putting more pressure on the skid, less on skis. Trade off is the front will be more tippy.

Also, check your front ski alignment. You should have 1/4 to 1/2" toe out with a bungie between the front of the skis taking up the slack . Wider toe out helps with turn initiation, and is the first adjustment I would play with after pressure...

I've been running my MTX with both stock and with skinz front end and it handles quite well. Top heavy because of narrow ski stance....sure, but I don't slow down to 20mph in the corners.

Mine is abear to turn with the mtx powder skis. With the stock mt9 ski it feels super light and easy to steer. Trade off is the push in the corners in loose snow but it is nice to steer though.

The front skid shock is where he is saying raise the air pressure not the ski shocks. Adding air to this shock will take some of the pressure off your front end.

How are they measuring ski stance. With the weight on the sky's or off. Weight off I get40.5" and weight on the sky's I get 43" centre of the spindle. I know I had to replace one set of spindle bushings because who ever worked on this sled at the dealer left out one of the washers and the other washer was on the outside edge of the collars and not against the spindle. This caused the collars to wear away at the spindle hole and let the ski slop back and forth. New bushings and washer tightened everything back up. Is there a certain way the collars go. There is 2 short one and 1 long one. I think I have the long one on the outside of the ski and the 2 short ones on the inside.
Is it save to let all the air out of the front shocks with the weight of the sled on them so I can see where they would bottom out.

I am going to try 60 in the front skid shock next time out. See if that helps. I am 240 dressed ready to ride. I think I have my front shocks at 70 psi. Might try 60 there as well.
