Ok so I took my bike up to the dealer he listened to it and said it sounded like worn rod bearings to him. But I have put 160 miles since I have heard this very light knocking sound, maybe its not and he wants to rip me off. Before I tear the motor down or buy a new one, is there no way at all to tell if its the bearings by testing it or something? The sound is coming from around the clutch area it gets quieter when I pull in the clutch but does nto go away, which makes me thing he is lying. He tells me 20 hours labor so I know I will buy a new motor before I have them fix it. If I fix it myself I was going to replace all the bearings and the crank, hoping the rods arent ****ed. I dont know what to do the bike runs fine except this sound. Can the throttle bodies being out of synch make engine noise such as a slight knocking? I have my new morgan carbtune coming in the next few days so I will synch them and see. I wish I could record it and post it. But I have know way of getting the sound to a file. There has got to be a way to tell what it is. The dealer said he could be wrong but needed like 3 hours to find out, bullshit. Mechanics please help.
