65 CB77 dies like its out of gas

[cgroom6]

My cb77 dies like its out of gas inexplicably. This can happen after ten minutes or 30. I just had the carbs and timing done. New battery.Petcock is clear. New tank and tubes nothing is pinched. New gas cap in the mail. This is ruining a really fun bike. I just dont know how far I will get and not be able to get back. It will usually start back up right away and do the same thing. Please help and thanks in advance.

cgroom6, Don't panic till after you have tried the new gas cap. That could be the problem,if not you will want to see if it has spark at the plugs next time it quits on you. If it does then its back to looking at fuel problems. If not then you should look at new coils and or condensers. BTW how is the point gap and timing? Kustommusic
