2016 sxf-350 starting issue

Recommended Posts

I have a 2016 SFX-350 and having starting issues.

Started off when I was at the track going round and it just cut out.

tried changing plug, and someone told me it could be fuel pump relay so replaced that too but still didn't fix it.

I took it to my local KTM dealership and they had a look put a take off another 350 on it and the bike started up so they said it was fuel pump.

I didn't fancy paying the £270 for a new fuel pump from KTM so I decided to get an aftermarket pump from ebay and I fitted that.

Now it turns over and attempts to start splutters and then cuts out.

Any ideas anyone?

Check to see if your bike has a recall some early models have a problem with the capacitor. If the bike runs you can check by starting it then remove the positive battery terminal and rev it up, if it shuts off the capasitor is bad.

I heard of a problem on the Husky 450 having a problem with a wire disconnecting that causes the bike to stall. If I remember right it's a connection to the frame. Maybe an earth.
