My Suzuki LT80 QuadSport starts and then stops within an intermittent short amount of time.

We will start it ride down the block just a couple minutes and it just dies.

It wont start again till I press the little reset switch.




Any ideas what's wrong with it?

 

You may need a new relay...located under the seat next to battery...


It may be heating up and shorting itself out...heat time would vary and could explain the "intermittent" nature of it popping the reset button


Make sure the fuse is the correct amps while in there...

 

The reset switch is only for the starter, nothing to do with the running of the bike. The only way I can see the bike stopping and the reset popping being connected is if the engine is seizing up. Are you sure the oil pump is working?

 

What year did they start coming with this button?

 

90's I believe...I have an earlier LT80 and it doesn't have the button...


Not sure about it "seizing up"...they seize and that's that...shutting down after warming up sounds electrical to me, but checking the compression is always a good idea when the motor is acting up...

 

not on the 89 not on the 90
Circuit breaker of sorts blows just prior to the main fuse?
Cool

 

"they seize and that's that"
I fitted a used 3hp B&S engine to a bale elevator on a farm, it would stop after 5 to 10 min running then restart after cooling down. I was sure it was the magneto, so fitted a new one, didn't cure it. Then noticed it was a little stiff to pull start when hot, took it apart and found some prawn had fitted a new piston but left the oil flinger off the big end cap, by that time the main bearings were shot from oil starvation.

 

Well...anything is possible, but 2-stroke oil is very different than 4-stroke oil...one is designed to burn off, the other is not...so in 2-strokes, when lubrication fails, everything else fails very quickly...
