Lexmoto Milano starting problem

Hi new to this site and just wondering if anyone can help.
My 125 efi won’t start, just had it in at the garage with this fault and low and behold it started every time they tried it,so felt like a Rite idiot rode it home no problems, left it for half an hour and won’t start grrrrrrrrrr. There’s a spark and it’s trying to start but won’t so frustrating ,anyone have any ideas
Cheers

 

How are you trying to start it ? run me through starting process.

 

turn key, pull in brake press start button.( not on side stand). Kick start doesn’t work either . Everything lights up and it’s turning over but just not starting, had a new spark plug with a good spark

 

While it's cranking over, open throttle slowly. worth a try. And check valve clearance as they are often to tight.

 

Have you got the side stand down? If so it won't start. Or maybe the kill switch on the handle bar. I believe you can disconnect the side stand switch to test if you have a problem with it!
