    Guys, I have a 2016 FE 501, and it can be a bear to get started. 93 octane non-ethanol, new battery, hit the starter button- it turns over just fine, but won't start. Wait for 10 seconds, do the cycle again without touching the throttle, repeat several times. Sometimes she starts right up, most times have to blip the throttle while cranking it to get her to fire up. Standard US ECU, the bike is stock. Frustrating to say the least.
    Without a key start, I never hear the fuel pump pressurize, I assume it has to do that while I am cranking it over?
    Once running- while holding the throttle steady at just above idle, the rpm's will not hold steady- the engine surges especially when cold.
    Any suggestions? My nearest KTM/Husky dealer is about a 5 hour drive away.
    Thanks,
    Terry

    Check the basics; Fuel screen, fuel pressure, valve lash. Balky starting in my experience has been due to tight valve lash. But I'd do the easy stuff first.
