Recently picked up an 05 Vector. Came with 2 sets of torsion springs. The owner told me that one set was strock, the other the heavy duty. My question is which should I start out with. I weigh 210, plan to ride not very agressively. Does anyone know how much stiffer the HD springs are or have any experience?

I have owned my 05 Vector ER since new and I have found that the stock spring is sufficient as I weigh 225. The setting is on medium for me. If you want to get aggressive, switch it to hard and that should do it for you. Check out all your bearings including the driveshaft as this has been a weakness on my sled. I have 5,000 miles on it. You will love this sled.

I'm not sure how stiff the HD springs are but if they can be set to low and its comparable to the stock medium, I'd go with them. I run stock springs on med and sometimes hard (200lb). I found that low is way to soft for me so a little stiffer spring that could be set low to med may not be a bad idea.
Start with the set that is already installed! You need to get a feel for the sled before you start to make adjustments.

I would start out with the stock springs, I weigh 180 and on the light setting mine is still to stiff.

The stock torsion springs are very good for all around use. I weigh 220 and the stock springs were good for me until I get very aggressive in the big bumps. I haven't had a chance to try out my Nytro springs yet to see if I like them but we'll soon see. The biggest plus on these sleds is a rear shock upgrade.
On that note, even though the torsion adjuster cam is marked S-M-H, it really does nothing more than set the rear ride height. The H setting raises it so it does not contact the bumper as early. Set the ride height first, then sit-in, then transfer. I'd recommend moving the round bumper to the front hole. If you bottom out with the bumper in the rear hole, your spine will be shorter afterwards.

remove the round bump stops.

grizztracks said:remove the round bump stops.
Lots of folks do this too. I chose to leave mine on but moved them to the soft setting (front hole) to slow the suspension travel before contacting the main bump stop at full bottom out. I've heard of some cracked rails at the main bump stop area (and other components) from harsh bottoming. Just my preferrence.
As stated above on the springs: "Start with the set that is already installed. You need to get a feel for the sled before you start to make adjustments."
