Kick start trouble?

The spring that returns the kick starter to the up position has a little hook that sticks into the case under the clutch cover. You'll probably have to pull the clutch cover off and see what's going on in there. You'll probably see the problem as soon as the clutch cover comes off.
 
Mine recently did this and it ended up being a broken case halve.

Pray to ur god it isnt the same!

Nah im just kidding it aint that bad to replace but most likely its a broken spring as stated above.
