I use the Boivan ETS kit as well. It definitely helps the skid "couple" but you will probably have to go to a lighter spring as suggested. With the ETS you will eliminate the "bucking" but it will be firmer.
Mmmm. Not really familiar with the smaller sleds. I see. That's kinda hokey, that they didn't put ACM on it, but the pics sure do show it's not there. Suppose there are other differences, as well. I'd still think about trying some lighter springs, though. Good luck.
Belleville, I have the same problem. Bought my wife a 01 mxz 500fan. The sled can only handle about 150lbs on it. Any more than that, and it fades out bad. Wifey not happy with it at all. Have been surfing hard to find a better set-up for the sled.If you come across any aftermarket products let others know.
