If you are going to pop the clutch to start it, I would recommend doing it in second gear and not first if your are on a loose surface (gravel, etc..) when my battery was bad I would push it down the gravel and try to start it in first and it wouldn't work, it just kept dragging the tires haha. After about 5 or 6 times of pushing it, hopping on and slamming it into first, i finally tried second gear and it fired up every time
. it gets old pushing it around to start it though, really old if you do it on a trail and there is no down hill close by. The few times I killed it on a trail, I had to push it halfway up a huge ass hill to roll back down and start it. not fun
