Jumping

[ncff07]

I've searched the boards and didn't see anything specifically to this so I'll post it. I'm still learning on my bike and have done some stuff to it but I'm stumped here. When I start it I do so out of gear most of the time unless I leave it in gear parked somewhere other than home. Ive noticed when I get on and ready to go when I put it down into first gear it will jump for just a second then be fine. Also noticed the times Ive been somewhere and left it in gear parking once I start it back up it will jump then too. With the clutch lever all the way in and in gear it will roll freely either way theres no friction whatsoever there. I did adjust the cable to within specs and it still does it but in gear and the clutch disengaged its still free. Any ideas?
