Can someone tell me what the total gap is on a stock set of Viper transfer rods?

Can someone also tell me what ride height I should be looking for when setting up a viper long travel in an SX?

Thanks!
 
total gap on a long travel pro action is 14-16mm with a thin spacer on the bottom.

set the ride height to make this gap equal top and bottom with all the weight on the sled that you will be riding with.

also set your front track spring so that when you sit on the sled, the front end doesnt lift at all.
 
It has bender adjustable rods on it, with about a .100 inch spacer on the bottom and a very thin one on the top. Haven't measured it yet but the rods appear to have a very small gap. I could probably totally close the gap by opening the rods up. I have never seen this small of a gap on my xtc or sx. The rear also feels very stiff, it is a skid that I picked up in the classifieds, and it supposedly has a big boy spring on it. I have it on the center setting, and haven't done any adjustments on it yet. I just bolted it into the sled last night. I am going to try and set it up today.

I know that you told me that the viper front end in the sx didn't want a lot of ride height. where should I set in up as a starting point? Should the tie rods be sitting level, or have a slight angle.

Thanks for the input!
 
If I set the transfer rods to the second line, I have 14.5 mm total gap. Shouldn't the bender rods be at about 4 or 5 lines for stock setting.

Yes. It feels stiff when I push down with my hands, but if I stand on the back bumper and jump on it, it almost feels to soft, and like the travel is limited. It almost feels like the rods are bottoming out. I have never messed with a viper suspension, so it is all new to me. When I first installed the viper shocks in the front, it looked very low in the front, so I put more preload on the springs to raise the front. Just guessing on the preload.

We are just starting to get snow around here and my first ride will probably be next weekend, and I need to trailer it about 3 hours to get to the decent snow. I hate to trailer all that ways and have problems. Just trying to make sure that it is set up right.
 
If bushings are worn at all in the pivot points it will bottom out on the rods.I found using the short stock spring on the rear big shock works better than the longer ones.You have to wind the adjuster close to the end but it holds the arz end up better.
 
I just went through and totally rebuilt the rear skid. Everything is new and tight. I just got everything back together, and when I sit on the sled, the rear hardly even drops. I am going to try and soften it up, and see what happens.
 
OK! If I measure the rear bumper height, and then collapse the rear till the transfer rods hit the end, I am seeing about 6 inch difference in bumper height, How much travel should the viper suspension have when measuring the bumper height? It doesn't look loke it is going up into the tunnel as far as it should to me. Doesn't the sx have 6 inches? I also have backed the main spring off so it has very little tension on it and the rear hardly settles when I get on the sled. I weigh about 250, seems that I should be able to collapse it with the spring set that soft.

The big boy spring must be a pretty heavy spring. Should try the softer position on the front adjustment, I think it is called the fra? I would buy a stock spring and try it but this late in season, I don't want to put any more money into it. I would like to try and get it to work with what I have for this year.
