Hey guys, so I have a 05 yfz 450 that's having some electrical problems. So first this thing drains a battery in a day of riding. It's drained a battery so bad we've had to upgrade to a motorcycle battery. But since I've got it the lights will not come on unless it is started, it will also not start unless in neutral, just last week the neutral light does not come on anymore, and just yesterday the battery is completely charged but it'll crank once and the battery won't even go anymore. Sometimes it'll crank and start and sometimes it won't. I've gotten a starter and coil for it and also a couple things that are not electrical but I have a suspicion it might be the cdi? Any help ?
