30 yamaha has intermittent power loss.It is the three cyl model but doesnt feel or sound like any cylinder is missing power just drops for a second or so then picks up again.This doesn"t happen at any regular time or for any length of time.Always starts easy idles well and runs without problem at low revs(most of the time). The plugs have replaced carbies have been clean fuel line replaced stop button and overheat lamp disconnected and reconnected incase they were faulty but no joy anybody got any ideas for me?
