08 TE450 runs great but dies unexpectedly

Recommended Posts

I just picked up an 08 TE450 which I thought had a fuel pump issue. I've had some older dirt bikes but fuel injection and husqvarnas are new to me.

 

The bike will fire up and run great for about 20 minutes. Then randomly it will shut off like it ran out of gas. I am forced to pull over and after about 5 minutes the bike will start again. Same thing, will run great for 20 minutes then turn off again. It's very consistent in its failure.

 

This problem keeps occurring even with the new fuel pump. I'm thinking it has to do with the ECU or something electrical. Has anyone experienced the same symptoms with their bike?

Great modern bike

4 out of 5, reviewed on May 13, 2015

Good brakes, good suspension, excellent power with efi. REALLY COMFY SEAT, have not noticed any excess vibration at all. Engine holds good amount of oil for type of bike. Really great bike. ONLY negative is fuel pump issue which would cause bike to stop when hot but after replacing fuel pump no problems. Fuel pump is a known fault. Other negative is 7 ltr fuel tank is ridiculously small 70-80km trail ride, so have to put a new IMS tank on to take it up to 11 ltrs.

I bet the vent in the fuel cap is bad. It's causing a vacuum and staring for fuel. Ride around with cap cracked open and see if that fixes it. If yes, pull the locking mech out of cap and make sure vent is clear. It's a small BB inside cap that gets stuck.
