hey. i gotta 99 ski doo mxz 600 and when i sit on it it goes down but i dont think it bottoms out (the spring) im not sure what it is..it acts like its not even working...i weigh 130 punds lol. and when i get off it i can pull the suspension back up and it stays but then it will go back down...any help? its all stock as well.

Worn out suspension it sounds like, sounds like a bad case, because i have a 86 phazer and the suspension is worn out but not to the point of it not returning to normal posistion.

Rebuilt sets are relatively cheap.

Rear height spring is shot and more than likeley the skid shocks need replacing. I have had to do both.
