I just traded up from a 2005 rs Vector es to the 2006 Attack. I'm tring to set up my sled for my weight and riding style. I tip the scales at 275 pounds :exc: before I get geared up to ride. I ride mostly groomed trails with a few side trips to open fields. I tend to ride a little on the aggressive side when it's safe. I average about 200-250 miles a day with a few 300+ days mixed in. I need info to get me close so I can spend time riding and not adjusting all the time when it finally desides to snow. This site has helped me in the past and I'm sure I can count on help again. 
Stock shock position is #1 click on 4th cam(out of 7). I was very "Jonny sceptical" of buying the heavier spring at first so I put the preload on clip #3 cam #1 and the sled handled very bad. I went back to the 2nd clip on cam #7 and the handling was great but I bottomed quite a bit over a 300+ mile ride. I just picked up my "heavy" spring and will install it tomorrow. Don't be "Jonny Skeptical" and waste your time..buy the heavy spring and install it right away, with low snow conditions you /we don't have time to waste. I weight the exact same as you and by the sounds of it ride the same. Hope this helps.

Thanks for the info. Let me know how the new spring works. I'm going to order one when I find the part #. Is there more than one optional spring? I've heard you can remove the shock assembly without taking out the suspension, but you have to have a special tool to remove the spring from the shock. Again thanks and hope to here from you again when you've tried the new spring.
Part # is 8FU-4789-10. It is best to remove the shock from the sled then compress the spring with a spring compressor. I've been using a strut compressor from CAP, it's big but gets the job done.

What handling characteristics were advesely affected when you move the clip to #3? I just moved mine but no I'm wondering if I shouldn't have.

I found that it seemed to teeter totter somewhat like the regular torsion spring suspensions do when you have to much preload on the center track shock. I would get better transfer on acceleration but when letting off the throttle it would all go back to the skis and steer side to side(dart) almost uncontrollable. I was pushing the corners alot also. This was all done on a lake though so conditions weren't the best. I did ride a friends attack the same night which was set at stock and his handled alot better. I believe if the stock spring is cranked up to the 3rd clip it puts the COG up to far, JMO.

Wouldn't a heavier rate spring have the same effect?MyOutdoors said:
I don't believe so, my theory would be that the heavier spring is the same length, just sprung "heavier" versus the stock spring needing to be preloaded(longer) to it's max. So I can get the same preload on clip #1 with heavy spring compared to stock @ clip #3.

There's probably some merit to MyOutdoors theory. Spring force is a function of spring travel & spring constant. Moving the clip to #3 for the stock spring uses up some of its avalable length, installing a fat boy spring has a different spring constant but also has all of it's available travel.
Guess I'll have to find out this weekend. I hope the handling stays ok, I was real happy w/handling before moving the clip, she just bottomed easier than I'd prefer.

I'm glad I have merit! Just kidding. I really didn't give the 3rd clip a chance in the trails, so maybe it will work with some more tuning. Give it a try and let me know. A $100 dollars is a $100 dollars and I wish I could have spent it on something else.

YOUR GONNA LOVE YOUR NEW ATTAK,
Get the heavy rate spring. I am 275 w/ gear.
I like to jump. This last weekend up in Muni I had the sled bottoming out quite often.
I have the heavy spring and I am going to move it to the secon clip

I got a chance to put about 300 miles on over the weekend with my new fatboy spring. Big improvement over stock. I go about 240 geared up to ride. I thought the ride quality was improved over stock and only bottomed once. I am running with minimum preload and varied between max soft and 6 clicks from max soft on RA adjuster. Probably the best $100 I will spend on this sled.
