If fuel / air is not right the spark plugs will be unable to ignite the fuel.
It would be over fueled at start-up and run sluggish until hot.

Could be as simple as condensation in fuel system and need a dose of dry gas or Heet. A little water in the gas goes an incredible long way. That is the least expensive thing to look at besides the plugs, airfilter and battery.

Today I checked and charged my battery today, also electrical connections (ok). I started it up and it started for a few seconds but it was sputtering and was struggling to stay at idle then it shut off and i couldnt get it started again (no smoke or leaks or any smells). Sunday I will be checking out the gas tank and then the throttle body as some of you suggested.

I would start with the easy stuff first like fuel filter and then the Crank sensor. If that does not fix your problem, then i would look at the MM EFI because they are known to go and when they start acting up most people just swap to a carb which is easy to do on this model.

I wasnt able to do too much to the bike but I took off the air cleaner and has a little oil in there. Does this sound like anything you guys have experienced and would this be something causeing my bad idle.
After cleaning off the oil I started the bike up and it did start but I had to hold the throttle a little so it wouldnt die but still was running a sluggish. Tomorrow going to take a look at the fuel filter and then down the list of suggestions.
