I need some help setting up my suspension on my 05 450r. All the shocks are stock. When I go to the track and I land on top of a jump, my bike hops back up and almost sends me out of control. Is there something I can do to help or prevent this from happening? I know the compression setting is on the top and the rebound setting is on the bottom and you can adjust the spring also but I don't know what would be the best setting. Also I want to lower my bike a bit. I know you have to loosen the spring pre-load but will this make my bike bottom out more? My shocks have the factory settings if this helps.
Hi Bryan,
You are experiencing SSSS, Sucky Stock Suspension Syndrome. Stock rebound screwed all the way in which you never want to completely bottom this out (towards - H) is still too fast, Spring preload backed all the way out is still too high and spring rates are too soft for MX. We all have gone through this and that is why we design and make our own kits. However, to get through temporarily, screw the rear rebound (rod end side ) all the way hard H and back out 1/2 a turn - Don't bottom this screw out hard, just lightly. Back off the rear preload all the and back out the front until the front frame height from the ground is 3/8 to 5/8" higher than the rear (measured under radiator and foot pegs with you standing up not sitting). That's all you can do brother until your ready to buy some suspension. Hope you keep us in mind when you do our value is one of the best in the country.
