I posted this about a week ago but i'm still looking for an answer. The bike (2006 yz450) runs great once started but the process of starting it is impossible. I can't start it unless i'm on a stand or leaning on something. Some times when i kick it feels almost locked up and have to do a slow stroke to get the engine turned over. i just had the clutch basket out doing a clutch, is there anything i could have done putting the basket back in while meshing the gears that would have caused this? The bike used to start effortlessly and now i hate it. Hot starts are worse than cold starts. I have not checked the valves or timing yet but i was wondering if anyone else has seen this or believes it's related to the clutch basket removal/installation. Thanks.
