Hi guys, sorry to bother you, it’s about a Ktm duke 125 2021, I was riding it and it died on me suddenly, I’ve changed the spark plug and the clutch cause it was slipping and now it won’t start it has compression it gives spark, injection works, but it won’t start, can’t you help me or give an advice?

Does it just keep turning and nothing happens?

Engines need three things Air/ Sparks / Fuel. So in order
1) Check you have a spark at the plug you put in , touching an earth.

2) re fit the plug turn the bike over a few times, remove the plug and check if its wet. This assumes you have fuel and the tank filler has been opened to stop any vapour lock

3) Lastly check the air filter hasn’t been damaged or blinded.

good luck

Yes

have you found the problem? I think you miss something because, if you have compression and good spark and your injector works - so the engine should start without any issues.
What compression you have on cold engine?
When you change the clutch, what have you touched ? Right to the clutch there is timing gear
