I help at my local army museum and we have a diesel motorbike. when it starts on idle it knocks quite at bit when you rev it up the knock goes. some one has said it would be a leaky injector but I'm not sure. it does not smoke any more that a normal diesel car any help would be gratly recived

It could just be injector noise, the best thing to do is get someone who is used to what a diesel should sound like to have a listen

Easy way to see if it's a leaky injector, will be that the engine oil will smell of diesel if it's been going on for any amount of time (but being in a museum, I doubt it gets much use) sounds like it could be running too advanced at idle. If the fuel pump doesn't have dynamic timing, then it will only run "quiet" after a certain rpm band. Anything less, and the fuelling's too advanced, and you get knock People who fit stationary diesel generators into motorbikes suffer this too - and older tractors that use the bosch P-pump, as they don't have dynamic timing either tbh, if it's not smoking, pulls well, and the oil doesn't smell of diesel.... leave it be. BTW, any pics of this little beast?  |
