My shifter is sticking and not allowing the spring turn action. I made a post some time ago in regards to my buddies wr450 having the same problem. He took it into the dealer and they repaires it under warranty. He really did not know what they did exactly, though it was some sort of clearance problem. Hoping that some one might have some history with this problem and could provide some details. Have plans to disassemble and see what we find after work tomorrow night.
