2003 Yamaha Viper stock setup with 1.25" Ripsaw track. Rider - 180lbs

I am mostly "aggressively riding" the trails but love to get out and do as much w.o.t. as I can too. Last weekend I was in a field with a friend of mine. He was on his Ski Doo 500ss. We were just going from one end to the other and although I can safely stay ahead of him the entire time I don't care for how close a 500 is staying to my 700.

What's the deal with that as I run into it every time I ride against someone else? I can feel the pull the Viper wants to show but I figure that the stock clutching isn't putting the power to the ground. I have wanted to mess around with the clutching but am not too sure where to start. If I was to toss a heel-x secondary onto the Viper, would it be compatible with the stock primary or do I have to put a clutch kit in it to make the heel-x work at all? I get right up to 70/75mph pretty quick, doesn't pull past that and takes forever to get me to 100. To get it to have that same pull from 75 to 100, would I just have to add a little weight to the tip of the arm and that's it?

I know everyone knows what I am referring to so I will certainly appreciate all your input.
 
48/34 or 48/36 helix, new red dot yamaha sec spring at 80-90 twist, red heel clcicker spring, 40-10 weights with 4-5 heel weight, 3.4 center and 4.3 tip. You want 8600rpm on top.

Direct from MrViper700 when i asked him...
 
You do realize that the 500ss is actually a 600 right? It's the pre-rev chassis 600 motor. So don't feel too bad.
 
I don't have a studded track either. I presume that for the recommended clutch setup to work at all, I need it studded .?. A 700 triple should waste a 600 twin....imo Where is the best place to pic up a sec and pri spring, weights and arms......I have a few catalogs that offer springs and what have you, but are the color designations similiar across the board of manufacturers and distributors? I assume this is the primary spring <Red Heel-Clicker spring> is that brand specific? Are you referring to the arms when you say "40-10 weights"?
 
Yea, you should be able to beat a 600. My buddy's Polaris 800 used to eat me. I stretched it to a 144, changed the secondary spring & helix, and geared down a tooth. Now, from dead stop or rolling, I beat him by at least 2 sled lengths. So studs or a longer track help. If you look under the tech pages, Turk has a good trail setup for the Viper. I bought all my stuff from Pioneer Performance. They have good prices on helixs/springs. You can also check under the parts classifieds.
 
If you havn`t yet,I would start with all the basic maint first like cleaning power valves , carbs , and clutches new belt etc.Then see what you are pulling for top rpm that way you know you are starting with the correct baseline.Yes you are correct agressive clutching is going to need more traction even a stock viper needs studs to hook up that power.
 
Studded track helps emensly.. Mine is picked and she hooks up great on the hard pack and icey conditions. lifts the skis right up. Motor stock , clutches stock, but I do maintain her very well.. Going to put a clutch kit in this summer and triple pipe her. Should be fun..
