I need help with what to look into next, my son rides this bike and his bike recently has became hard to start, within the last couple rides. Now I cant get it to start using the button or by kickstarting, it will jump start. I've checked out everything I know to check. I've cleaned the aircleaner even though it wasn't bad, checked to make sure it is getting good spark,it is, and plug looks good, it is getting good fuel flow, and I checked to see if the jetts are clogged and the battery has a good charge. I dont know what to look at next, so if you out there might know PLEASE hit me up with some advice. My son looks like he just lost his best friend, I've got to get it running before sat. big ride for us and he dont want to miss it. So please help!!!!!
