wont start

i did not ride the sd for 5 weeks.
Changed chain and sprockets this week and today fired her up for the first time.
Ran for about 3 sec then stalled.
No f1, smell petrol odour from exhaust.

Used forum search,....checked tipover switch. Switch works. Removed it and got f1 error, bike wont run.
Checked sidestand(should not be the problem, just in case...)
Checked all possible stuff with tuneecu.
It cranks but wont start....
Help?

Check QR fuel line connector.

When you turn the key does the fuel pump prime dude?

Have you disconnected the fuel line quick release? Make sure its properly back together.

Hum.....When I read your above words, it leads me to believe you removed the tip over switch but did not replace it.

If that is the case, you need the switch in place. You can't just take the tip over switch out without other mods to make a complete firing circuit.
