fuel pump

I posted this in my new to FE570 thread but thought I might get more eyes on it here. I have a brand new issue. I think it's a fuel issue based on some research and tips from Rainerio on here. About 5 times in a few hours, mostly on downhills in 2nd gear and engine breaking or just...

My Husaberg 390FE 2011 does not start. I only have 5v in the switch to the fuel pump when I press the start button. But the starter engine is spinning as it should. Anyone who has been involved in something like ?? The motorcycle has been around 70 hours. Thank you for all the answers. / Daniel
