God knows what the sound is. Generally its worse when cold, but not always. Sometimes there is horrible vibration from either side of the engine felt in the footpegs and another day its fine?????. Sometimes the noises and vibration make it sound like its going to explode then they go away. I know the crank shims are fine,the crank has been reground, small ends replaced and rebored 2 years ago. So top end and or timing are places to look. I know there is some clutch wobble but I need to replace the mainshaft bushes so thats one possible source of vibration. She burns some oil but not enough to smoke probably guides?. So yeah I don't know anymore maybe top end off over winter.
