I'm sure this has been flogged to death but can I please have the definitive answer on whether it's actually possible to get a smooth tickover under 1400 rpm on a 1977 CB550K3 and what is the true source of the cacophony of noise from the crankcase at anything lower than 1400. My "new" bike has exactly the same as my old one and I've done everything I can to balance my carbs (gauges, airsscrews, prayer) and it's still lumpy below 1400. Also how much choke do I need to use to start it from cold because if I open it full it refuses to fire? I'd add that on the main jets over 2000rpm it flies like a bird. In passing I read an MCM article some 30 years ago that said words to the effect that 550K owners simply have to accept that on tickover it sounds like someone has thrown nuts and bolts into the gearbox.
