Today when i was going to work, while cruising at 120 km/h , i changed lanes to make an exit from the highway, and as i changed lanes my bike lost power, throttle became unresponsive. Bike slowed down, i pulled over to the right, and when i was doing about 40 km/h the bike stalled. I pulled over, checked no leaks, tried to start it again, engine cranks but doesn't start. then while i was waiting for a tow truck, bike cooled down to point where it would need a choke to start, so i gave it choke, i was able to start it. turned the choke off, throttle was still very unresponsive, bike was reving very rough, and as soon as i rolled off the throttle, bike stalled again.

so i had get it towed, now i am try to think what should i troubleshoot first. It seemed like bike is not getting enough fuel. And when i was cranking the bike, seemed like fuel pump wasn't making any noise. any other suggestions or links to similar threads? Thank you!

 

If you haven't recently done any work on the bike (possible pinched or disconnected hoses), fuel pump is where I would start.

 

Well i have worked on the bike 2 days ago, did a tune up on the ignition coils and all that. So, i guess i will start with air control valve hoses and stuff because i kept twisting them around quite a lot. thanks!

 

you should feel the fuel pump energize after the bike has been sitting some.. it will click every now and again while running too...
