I just picked up an 01 yamaha yzf-600r the other day and it ran great, now granted it is cold as can be (30-40) i fired it up last night and ran about 5 mins down the street, let it idle for a few mins and then shut it down, and about 15 mins later tried to fire it up again and no dice, tried 4-5 times about 5 mins apart and nothing, and then finally it fired up and it ran great the whole way home, got home and shut it down and it started right back up... then this morning tried to start it and same thing, real hesitant but then it finally fired up... Tonight went to start it and first touch of the button fired right up WTF???

Just filled it up with 93 octance the other day and ran lucas carb and injector cleaner through it>> any thoughts
