I have a 2017 KTM SXF 350 which starts fine off the button but then randomly stumbles and cuts out. It will start again no problem and rev fine, but on tick over it will again just randomly cough and stop. Any ideas? Thanks

Replace in line fuel filter.
Fuel pump( if you have a buddy with a KTM you can try their whole tank.
Check all electric connections and ground wires.

I’d start there.

When it’s off, and you tap the button, can you hear the fuel pump prime?

Mine did the same thing. And, you couldn’t hear the fuel pump prime. Turned out to be the computer. Put a husky 350 computer in it from eBay and never had another issue.

Cheers guys, I changed the in line fuel filter, and just now cleaned every single electric connector on the bike. Also took plug cap off and blew it out. I also turned the idle up slightly. Starts fine, runs fine, revs fine, just a slight misfire every now and then but not stalling once warm. Got a feeling its spark plug or water somewhere other than a connector. Was fine all day when I rode it 2 weeks ago. I'm racing it tomorrow so got my fingers crossed

A nice clean air filter?

Could also been some bad gas or water got in the tank?

Raced the bike today, no problems whatsoever all day. Must have been water in somewhere I think
