Got a strange one here.
My first KTM RC390 and its a nightmare

-RC390 w/stock ECU, modded everything else. Always fires up but stalls while idling will idle decent if getting it hot with reving throttle
road ok for 30+ mins then wouldn’t go past 75mph in 6th gear full throttle just chokes
- Stalled at traffic light, cranks but wouldn’t start, bump started and ran ok for 10 mins then stalls while coming to stop, cranks but no start, bump start nothing, towed it home
Found a kinked fuel line going to injector, replaced it, replaced fuel pump too,
still no start, Has spark, has Fuel, Cranks normally, then found broken spark plug tip, replaced spark plug, still no start.
Just cranks and cranks!
Most unreliable bike Ive ever owned
Any help please?

Might consider the gear shift sensor/cam shaft sensor. Any Check engine lights? I had that issue with mine last summer.
