4rt wont start

Why are you pressing the kill switch at all when trying to start it? 

This is one of the two known ways to reset the EFI system if it's having trouble starting.  

I am not exactly sure what it dose to hold the kill switch or open the throttle fully, however my theory is it stops the spark and causes the bike to cycle without the system inputting any fuel.  This in turn clears the cylinder, at least enough, of the over fueled mixture for it to start and tells the ECU to recalibrate.  

I would expect there is more to it than this but it's my best guess.

Problem solved.  Changed the plug and moved the bike to a warm garage, was in a steel container.  Starts no bother on 3rd kick.

Thanks for all your suggesstions.

Cheers

Dont know if it works , I heard some 4RT owners in cold climates install knitted ''Tea cozies'' on the cylinder/head to aid cold starting...:( Good to hear you got sorted, Keep your feet on the pegs:thumbup:
