wont run once warmed up

[justmount1]

ok guys my 80 550L is still acting up i dipped the carbs all new jets new plugs new battery air screws set at 3 turns out new p/k new fuel hoses. this damn thing will start like a champ when it is cold, but when it warms up it dies and wont start back up. what do you guys think?

Coils getting hot and cutting out...

Did you ever have it running right? Is it possible that it's spark as opposed to fuel?

If it dies when it warms up, that sounds like it could be too rich. If you don't really let it warm up and just ride it before it dies, does it do decently on the throttle?

edit: yeah, I agree that it could certainly be the coils getting hot. They probably won't get quite as hot when you're moving as when it's sitting still, but if it'll cut out on the throttle I agree that it's ignition.

Take an extra plug with you, when it quits Pop the plug into the plug cable & check for spark. Does it make any difference if you run it on prime ? if it has stock coils? i would be checking the ignitor

Old igniters quit hot first and then quit all together.

sounds like it is time to look into a dyna ignitor and new coilds in the near future. well ty guys and yes it ran fine for a day or two once i got it put back together and then went to hell from there

ok so the bike has been running for about 20 mins now and idling fine. i just put a charge on the brand new battery that i had already had in it. i am leaning towards a bad r/r. any thoughts?

check the stator papers, all of the tests are pretty quick and easy to do.
