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???

So i changed out the plugs and it ran great... sitting at a stoplight and accidently hit the kill switch and it shut down, flipped it back to run and it fired right back up... 30 seconds later the bike completely cuts off... and wont start back up after numerous attempts...

have my buddy come load my bike in the bed of his truck and then get home and it fires right up again... any thoughts
