I've read posts about the 2 carbide skiis like the Ski Doo setup,but has anyone tried the new dual carbides that bolt right into the stock Yamaha USI ski.I've got a 2001 sxr7 that absolutley rails,could these possibly make it even better?Let me know good or bad.At $75 cdn each I could buy 2 sets of regular 6" carbides for the same price.
 

I owe a 2001 srx7 also that handles great, but i got a 2003 yamaha venture for the wife last year that darted around worst than any sled i've even owned. So I put a set of the 4in Dooly's on it. It was the best $$$ spent. The sled doesn't dart at all and corners better with less preload on ski's For your sled the DY6-6550 are $100.00 for the pair And the dy8-6550 are $140.00 for the pair (apporx)
 
There is a downsize to these though, if you want to save weight 'DONT' get them, they are very very heave for carbides................ I have the Simmons dual keel flex ski, love them in all conditions. and they are lighter then stocks!
 
Just curious, but if your wife on that venture doubled back on her tracks, does it dart and follow the ruts? I'd hazard a guess that your sled darted because of too little sit in for your wife's weight, and the result was too much pressure on the front of the skis, causing your darting. There's a much cheaper fix than $140 carbides!

If you feel like it, check out my article on darting in the Tech Page. It should help demonstrate what most darting situations are caused by.

I'd also say that a Venture, being a longer tracked sled, and having heavy springs, would require a different ski bumper than a standard sled. Yamaha doesn't see it that way, and we wind up with some darting sleds from too much pressure at the front of the skis.
 
To VMaxJohn: To your first question. If I or she follows the same tracks back, the sled doesn't dart at all because the dooly layed a straight line the fisrt time by. As for the Lbs per rider, The sled darts more with me on it and I go 100Lbs more than her. But could that be cause i ride more agressive and expect more.
As for tinkering with my sleds to get them the way i like, I will do it for my SRX and go as far as putting it on my racecar scales every year also setting my bump steer and akronym. If you have the tools why not.

But as for a sled the like the venture with different people riding all the time 1 or 2 or me letting a buddy use it. So, the Dooly in my opinion is the easy fix for the situation for just getting on and riding

Thanks for your help, please read my last post maybe you can help me out on my electric problems

possible fix

Not sure if you can do this on a Yamaha, but on all our Polaris sleds we took the rubber bumper that sits on the ski saddle (the ski spindle itself kinda of sits on top of it) and we turned it around the other way, sort of backwards.
This results in more of the ski pressure being put on the back half of the ski and reduces darting.
Its true that you could also just adjust the limiter straps to reduce the ski pressure, but I personally dont like to do that because I want the ski pressure to aid in cornering. However if many different people ride the same sled, all of which are of different sizes, its kind of hard to set it up to their weight.
 
Turning the bumper around on most Yamaha's would probably be too much, Poodles use a very small rubber (that came out funnier than expected). I've thought of also cutting the front of a stock Yami ski bumper, but that's a bit more permanent than a shim. I suppose once you get it just right with shims you could then wack off how much you need. Should have the same results.
