Bike stalls at 50 MPH
I use my bike to commute in a big city and usually stay off freeways. The highest speed I will go is usually 40MPH. However, today I decided to take it on a short ride through the interstate going through my city. After riding my bike for several minutes at 50MPH it stalled in the middle of my ride. I eventually fired up my bike again but after about ten minutes of riding it stalled again at around 35MPH. The engine just went silent. Headlights and everything else were still functional.
What is the issue? How can I fix it? I looked up several related forum topics: -2003 gz250 stalls at highway speeds viewtopic.php?f=3&t=3484 -higher speed "stall" viewtopic.php?f=7&t=2480 Thank you! Login or Register to Remove Ads |

Re: Bike stalls at 50 MPH
Try to duplicate the ride under safe conditions and wait for it to stall again. Open your gas cap and listen for an immediate sucking sound at the tank opening. You may have a plugged vent which is causing a slight vacuum and stopping gas flow to the carb.
Also check the oil level to see if is down. A very low level could likely cause the engine to overheat and heat seize temperarily. |

Re: Bike stalls at 50 MPH
If you stall at highway speeds, wont the back wheel lose power and lock and cause a skid ? Like if you stall on a turn, you fall over, correct ? Whats the difference in stalls and different speeds, what does the bike do at both speeds ?

The wheel will roll in gear and not lock up, same as turing off or running out of gas. You fall over because of gravity. not enough speed.

Re: Bike stalls at 50 MPH
Had a 125 2 stroke try to heat seize many years ago during a really hot day flat out on a highway. It would buck a bit, loose power and then come back to life. I had to remove the large home made mudflap to give it more air flow to the engine.
2nd wife had a complete lock-up with a 175 Yamaha at 30 mph on gravel. She road it out and stopped safely. It appeared the front tire kicked a stone up and it lodged in where the chain wraps around the rear sprocket on the bottom side. No damage but it could have been a serious get off in gravel. She had pulled in the clutch soonest but that didn't work at all. Had to be a stone that jammed the wheel. |

Re: Bike stalls at 50 MPH
Probably stalled in traffic somewhere.
