was running just fine, but while waiting on a new battery to charge I was jumping off the old one and I must of let it go to long and now nothing works at all. I now have new charged battery, new starter relay, fuses and cdi, but still nothing. I think the only thing left to replace is the voltage regulator?

 

I've found that the starter was shot. replaced it and cranks, but no spark. new cdi,volts reg. battery carb. spark plug. maybe coil?
