Suspension straps

[Snowshovel]

I bought a used 03 Mountain Viper and a friend of mine told me i should dump the stock rear struts that limit your suspension travel and go with rubber straps? Where is a good(cheap) place to get these and how hard are they to swap? Ive never wrenched on a snowmobile, however i have been wrenching on jets for the Air Force for 21 years, so i am mechanically inclined. Any help is appreciated.

Mountain Performance has that kit. Its called a transfer enhancement kit. Click this link and scroll down. http://www.mountainperformance.com/y...suspension.htm Eric

Excellent thanks for the help SRX, it says they are adjustable, is there a baseline or standard spot on the straps to start out at? Or just loop them and try to get it about where the stock struts are to begin and fiddle with it and see how different spots feel?

There are holes in the straps just like the front stock straps if I remember right.

I put a set on my 03 RX1M and from what I remember the kit comes with instructions and a 'base' setting, and then recommendations on adjustments.

Basically what this kit does is uncouple the rear skid and allow you to get the skis in the air during hard accelleration. (Wheelees if you go the power to do it)

The kit is worth it IMO.

Ahh ok thanks for the clarification TMK, I will see if the local Yamaha dealer has a set and then if not get from the site SRX recommended.

You can make your own very easy, Thats what I did. The transfer rods have to be removed fromt he sled. This is the hardest part of the job because the large upper idler wheels are pressed onto that shaft. One wheel has to come, then you can slide the shaft out the other side and remove the transfer rods. Now, you have to cut the end of the rod off to use it as a spacer or if you want to save the rods make a set of spacers. IF... your going to cut the rods off, then you can skip messing around with removing the wheels and shaft and just cut the rods off with a cut off wheel or sawz-all. After the rods are removed you just use a strap to limit the amount of travel.

It does remove weight and helps weight transfer but IMO hurts the ride quality. Eric

Hmmm your last sentence there makes me wonder if its worth it SRX, being as i just bought this sled i think i will leave it as is for a few rides and then make a decision.

I bought one kit for my '00 MMax then I have built 6 or 7 sets for some other people based off of my kit. Not hard at all. Finding the rubber strap is the hardest. And that is not to hard to fingure out.

BEST Thing you can do for a Yamaha suspension, is throw it in the dumpster.

Buy a Poo or Cat skid, MUCH better in the mountains. I prefer the Polaris myself.

I didn't think it could make that much difference in performance of the sled, but it really did. My old MM with the stock skid was a dog compared to my RxTon with the Poo skid, now that the MM has a Poo skid as well, it climbs with all the other sleds out there, spanked a stock Apex Mtn.

The hardest part is measuring where to put the holes for mounting.
