yeah listen to these guys, you do not want to dare try starting it without rings without causing serious problems to motor or self... just wait on those rings to test your clutch, its worth the wait... those magnetic parts that you were talking about are for charging the battery its how bikes do it, they dont require much power to run seeing that they've only got a few electrical systems, most likely your bike also has a magnito so that even if your battery is dead, when you kick it, it generates enough power to spark the plugs and thus start the bike... its a really inventive system.,... sometimes i wish my car had a kickstart with magnito
