2007 Suzuki LTR 450 - Wont Fire Up!

[pokerdad911]

I HAVE NEW PLUG IN IT AND CHANGED FUEL FILTER. battery IS GOOD. I CRANK IT OVER AND IT CRANKING, IT FIRES UP FOR A SLIT SECOOND BUT THEN BACK TO IT CRANKING. I SPRAYED SOME STARTER FLUID IN AND IT STARTS AGAIN THEN SHUTS OFF. SO I KNOW IT WANTS TO BUT WONT STAY FIRED UP. WHAT COULD BE THE PROBLEM? SOMEBODY HELP!!

if you take the spark plug out and see if it's bright blue, the electrical should be ok. i would guess the carb is dirty and needs to be cleaned. float might not be seated properly or a jet is clogged ...

+1 for a dirty carb. How long has it been since ridden? Possible water in the tank?

fuel, air and spark,,,check your compression too....good luck!!
