I have a 1999 yz400 that I recently rebuilt, I have almost put everything back together but have a quesiton before I go any futher. I just put on the kick start and tried it, everything seems to turn over fine but the kickstarter does not recoil back up it just stays where ever you stop it. It goes back easy if you push it back. Is it possible it does not return because I have not added oil yet?, or do I have to rip the side off again? any help would be greatly appreciated as I really want to get out and ride.
