I just picked up a Kawasaki kx125 2007 about a week ago and when i start it and warm it up for a little bit and pull the clutch in and push it down to 1st it shuts off and i put it in neutral and try again and same but if i give a little gas it goes in gear and if i roll a little bit and pull clutch back in and hold it for about 3-4 seconds it either dies or startd rolling a little bit ive tried adjusting the clutch lever a little bit but i feel like it isnt doing much all help needed.
