Will it kick through because today i was messin around in the backyard not realizing i was riding most first gear and fell over and it made clank noise so i shut it off and i got up and tried to kick it but it wouldnt kick through so i took the head cylinder off and it was in good shape , the crank was not locked up so i took off the right case side by the clutch and it still wouldn't kick through so im debating if its the crankshaft or output shaft
