I think I saw this before..but here goes. I have a 07sg. Sometimes it wont start...no turning over...dead. I can only start it if I turn everything off. The run button & ignition. This only happens...sometimes. I have tried just turning off run button to no avail. I checked all wires to the battery...all seem tight. Any info would be appreciated. Thanks, Tom

 

Here goes a shot in the dark. On mine I rode in the rain too mush and the terminals in the ignition switch were coroded all green ans fuzzy. I dissassembled the switch sanded all rotating contact points and coated everything with dioelectric grease. Thats all I got!

 

Check your crank position sensor. If it's faulty bike will not start or will run like chit.

 

Thanks for the feedback...where do I find the crank sensor?

 

Just above and to the inside of the wires for the stator. front right of the crank case.

 

If I shake the ign switch...I can get it to work!

 

tear it apart and go through it. sand the contact points and use plenty of dioelectric silicon grease. just my 2 cents.
