So my 650sx will fire up awesome the first time you start it to go riding.. once you ride it for a little while and you shut it down.. its starts really hard when you try to fire it back up.. You constantly have to keep turning the ski over and over and then it will finally start to idle.. once you try to give it any throttle it will die out.. you just have to let it idle and very slowly give it throttle for about 2 mins and then it will come back to life and run mint again until you shut it down again... it also has some low end bog.. I cleaned both high speed and low speed jets.. any idea's?
