Sometimes blend tree do not work

Hi,I have created generic animations in unity where bike rotate to its left or right depending on what axis user is pressed.

I have created several right turn animations though out of those animations,only couple of work when blend tree parameter gets changed.Other remain same and does not effect bike.

When I use “loop” to true in other animations ,it do work but loops continuously.

I am using only one right anim at a time.

Plz help in

ok found it…at end of any clip it should not be reset to its orginal position.Let blend tree do it in idle
