Stalling @ 70-80mph

[BigD_83]

i rode in to work today, and it started stalling again, it was like if 2 cylinders were to stop working, i heard the carbs back firing, and poping but yet again i pull over the side of the road and all of a sudden, back to normal, i think its a carb prob!

Not to send you chasing your tail, but something to keep in mind if it turns out not to be a fuel delivery issue.

One coil cutting out on you at speed would certainly feel as you describe above

Can you recreate the problem if you keep it running at 60mph for awhile?

definitely, it happens every time i stay at a steady mph, on a FREEWAY, not the city

Is that an inline fuel filter? Try eliminating that. If you need it, you must have rust in your tank, and probably rust in your carbs. If you don't have rust in tank or barbs, you don't need a filter. It might be the resistance that the vacuum from the carbs can't overcome at speed, and your motor is starving for fuel after a long run.

ok ill remove the filter, and give it a run in the morning

It's a 79, do you still have points ignition?

[SOCKinside]

Points ignition? I have no idea, how can I check

Yes. 1980 is when they switched to electronic. Remove the small cover on the right (sitting on the bike) side of the engine to see what you have and to check the timing.
