I am new to riding and bikes in general. I started with an '89 Sporty. It has been running great, but lately it stalls at random times....I could be cruising along the highway then it just cuts out. I managed to get it home, but only after having it stall numerous times...I coasted into my driveway.

Any ideas would be truly appreciated.

Thanks

 

Had an 88 Sporty that used to do that. Turned out to be a bad ignition coil.

Check for loose electrical connections in the ignition wiring for starters. Maybe the main circuit breaker.

To help narrow things down, do the lights go off when it quits? Does it start up immediately, or do you have to wait a while to start it?

 

It starts up pretty quick after it stalls. Typically, I will be cruising down the highway, then the motor will stall. After I coast it to the side, I can usually start it up within a few minutes and get a few miles out of it before it stalls again.

 

Do the lights go out also?
When it stalls, does it just stop running, or kinda sputter a bit first, running rough?

 

Not sure about the lights. When it stalls, it just flat out stalls. I will be cruising, then it will just stall without warning. So, I pull in the clutch and start it again as I am coasting, then within minutes it stalls again.

 

Big hitters on those...
1) Vacuum petcock failing - running out of fuel
2) ignition module overheating (especially if rotor cup has been disturbed and is contacting it)

 

Take the gas cap off and see if that fixes it. Sometimes the vent gets plugged. It's a long shot, but it's a free test, and easy fix.

 

i have the same problem on my 1995 flht,,it runs great then just cuts off,,, head lights and all other electracle still works, it has to sit for about 30/40 minutes it starts back up and runs for about another 40 to 50 miles,,,sometimes even further,,then shuts off again,,over and over again,,help,,,anyone suggest an idea for me

 

i would start with replacing the main circuit breaker. 15 amp breakers are available at any auto parts store and are about $8.

 

main breakers are 30 amp. sorry about that.
