Raptor wont turn on

I have a 2005 660 raptor and i bought it feom my friend it didnt run because he had burned his cdi box. So i bought the cdi box and bought a new coil and spark plug i also cleaned the jets TWICE and it wont turn on it just trys to back fire a liitle. It has spark o dnt know what else it could be to cause it not to turn on

if you bought a cheap cdi it could be that i would also test the stator and pickup coil. it could be the carbs as well they are very difficult to put back together without a manual. some of the hardest i have ever done. look for vacuum leaks around the carbs and in the diaphragm lids. test the crank sensor

just because it sparks does not mean the cdi is not bad, its less likely but it still could be the issue. did you check the other things?
