I have the above mentioned bike and redone almost everything on it.  She starts with the push of the button everytime and runs solid.
I came back from a long ride and turned the bike off.  35 minutes later went to start the bike and I had no power (no lights, nothing).  I changed the battery (with a fresh charged battery)  still no power.  I check all my connections.  I tried kick starting the bike and nothing, wouldn't turn over.  What could have happended, what do I need to check?
Thank you!
Answer -
Roland, Did you run engine low on oil? Sounds like you might have sized the engine? Get back to me .Glen

Answer
Roland, I'm sorry I thought you said the engine would not turn over?? Anyway you have lost electrical power?? I would first check the fuse's?,Then check to see if connections we're good at battery?,Check the ign. switch?Check the bar switch on right side bar?,check to see if the grounds have gotten loose at switch?,Check the starter wires? Sometimes if a bike has been setting for a long period of time,A wire might be damaged do to the elements (wind,water,weather,rats,mice,) Hope this helps.Good luck.Glen
