I´ve had a really hard time to start the bike for about the two first month of the summer. The problem was the stator on the left side of the motor. Luckly i have been able to find a uses one. Those thing cost near 300$. Now the bike start on the first two shoot with the decompressor taken out.(I´m to lazy to put it back on). If the crank stay down and doesn´t come up again you might want to take a look at the spring crank. They broke sometime. The last thing i notice is a short on the flasher relay that put the battery down. But this might not be a typical problem for the bike but more due to the mud, water, sand and street.(hard life heeep)
