I have a 99 YZ 400, i had my forks serviced recently and have set the compresion and rebound to the stock settings. But now when i push them down they dont fully return, and have about 3-4 less inches travel. I can pull them up but as soon as i push them down they only return 3/4 of the way. What can i do to fix this. My rear shock also sags, but feels like it still has good rebound, should it have free play or somthing like that? thanks for anyones input.
