Hi I have a kxf 450 efi 2014 that will not start. I have a spark and had the fuel pump kicking in on 12v to make sure fuel was pumping through. I have poured petrol into the cylinder and easy started into the intake but nothing. I had the head off to change the cylinder and piston and since then it won't start. Sounds like it has good compression when kicking it over because of the whoosh noise out the exhaust. I am baffled with it and it's killing me just kicking and kicking it. Any suggestions or anyone can help me check a few things by video link etc.
thanks everyone.
Andrew
