IMPORTANT ENGINE STARTING INFORMATION

  • You may want to consider setting up the bike on a stand for a solid starting location at first until your confident
  • Turn on Both Fuel and Choke
  • DO NOT open the throttle (do NOT turn the throttle)
  • Move the starter down until it gets stiffer, your looking for top dead center
  • Let the starter come back up and give a full strong swift kick ALL the way thru
  • REPEAT (If necessary)
  • DO NOT KICK RAPIDLY
  • When warm just do not use the choke

Flooded Engine:
IF your flooded , pull the plug, kick it over about 10 times WITH THE PLUG OUT
Put in a NEW PLUG

One more thing:
At times it helps to just crack the throttle a tiny bit to let air in.
