Hey all, long time since I have been on here but I have a question. I have an 04 with 36,000 miles. No prior problems except the TPS. New noise sounds like someone knocking on a plastic or steel door. Noise is inconsistent and not associated with RPM's I don't think. It does it every time but not at routine intervals like with a valve tap. It does not happen when just sitting still reving the motor in neutral. Only when taking off under load or moving under load. Does not happen when coasting. Coming from lower to lower left of motor. Oringinally thought it could be the chain but the more I listen I don't think so. I am sure it does it at higher speeds as well but difficult to hear over wind and engine noise. Anyone else with similar or higher mileage ever have this type of noise or anyone have any ideas as to what might be causing it? I thought posibilities could be something in the gears, or chain, or possibly clutch. I am going to try taking off the chain and put it on the center stand and try it to see if it does it with just the front sproket turning. Any other suggestions before I start tearing it apart to check it out? Also hope this isn't a repeat topic. I did some searching and couldn't find anything, but like I said it has been a while since I was last on here so I am sorry if this was brought up before. Thanks.
