I have a noise i have been chasing for a while now. It actually sounds like it is coming from the valve train. I had hoped the noises were from my transmission that I rebuilt in another thread recently and that did take care of some noise, but not what I'm hearing now.
I did a 107" kit and t-man 555tq cams last fall. The noise started about 300 miles into the break in and I initially thought it was pinging, but after dyno tuning it was still there. I spoke to Frank about it last week and he mentioned that the cams I have are noisy, but my noise is to severe for that I think. I tried the rag over the air cleaner he suggested but it was still there. I met up with Hutmo and Dmize last weekend and both heard my bike and also thought the noise was a problem.
Before heading to Pittsburgh last weekend I had pulled the Rocker covers for a visual and readjusted my pushrods in case they had moved since my build, but everything appeared fine.
Scott at Hillside mentioned in a thread about crank problems to keep an eye on oil pressure and that crank runout can contribute to valve train noise and low oil pressure. This popped into my head on the way home from Pittsburgh so I started focusing on the gauge and realized my oil pressure was between 16 & 18 pounds in the 2800 to 3000 rpm range. It should be about twice that.
I drained the oil and pulled the filter yesterday. I am using the K & P reusable filter which has a magnet built into it and it had a pretty sizable glob of metal soaked oil on the magnet. About the size of a marble.
I pulled the cam chest apart and checked the crank runout. It was less than .003. I didn't notice any unusual wear marks on the cams, oil pump, or crank.
I'm going to swap the cam plate and oil pump for either the Feuling, or SE one. Perhaps the low oil pressure is causing my problem, but the amount of metal on the oil filter has me thinking something worse. If I was a betting man I would have put money on the crank runout being horrific, but not so.
Any other suggestions of things to check?
