I have KTM 50 Adventure senior. 2 stroke mini mx bike. Bike ran when I parked it. Now it won't start. Getting fuel, getting spark.Won't even fire on ether. Little bastard is just dead. Compression seems fine, not tested. Pull the plug and kick it, I see spark against the head. I even shot ether directly in the cylinder and replaced the plug...not a hint of fire... I'm baffled... What gives? Any ideas? Thanks in advance.
