ok..this is what happened..just got the bike. kid took it out a couple times no problems..he ran out of gas one time, and like an ...... i drained mixed gas out of my bike not realizing its oil injection! so it starts revving higher and making less power so he stops riding.... drained gas..yatta yatta...but straight gas in it, go riding, no problems...he crashes and i cant get the bike started again. cleaned carb, checked for spark, new plug..nothing....so i go ahead and check the reeds and put in a new piston. reeds are good...put it back together and nothing again....not even trying to start. i even against my better judgement sprayed some starting fluid with no results... i took the plug out again and kinda noticed the spark is white..i am seeing things and is this my problem-not have blue spark? what else can i check...gotta get the kid riding!
