Engine Noise/Pinging? - Jamil Torres_imp - 03-31-2016 So I have ridden about 2300 miles on the cb and it seems to have developed a pinging at idle that was not there after the first service. I noticed that it does not come along until the engine is warm or I ride on a warmer day. Sometimes I can get it to come around by accelerating pretty hard and shifting at around 4k rpm. Is this normal? RE: Engine Noise/Pinging? - the Ferret - 03-31-2016 You are probably just noticing the fuel injectors making noise RE: Engine Noise/Pinging? - immgunn_imp - 03-31-2016 It's not impossible, but it's challenging to make an engine ping at no-load idle. Try holding a long screwdriver or socket extension to your ear while touching it to various parts of the engine, i.e., the fuel injectors. RE: Engine Noise/Pinging? - Jamil Torres_imp - 03-31-2016 I'll do that and see if I can pinpoint it. I tend to worry a lot because the 1100 is my only running vehicle for the moment. Thanks for the replies. RE: Engine Noise/Pinging? - kmoney_imp - 03-31-2016 You will (or at least I do) notice slightly more valve-train noise at idle as your oil shears and thins out after some use, but I would probably agree with others that it's probably just the injectors you're hearing. |
