Well this chapter is closed, hopefully. I got it all back together, and after the fact realized that I had left the spark plug wire off...
. Off with the seat, off with the tank...
Got it all back together AGAIN and fired it up. Ran real smooth. A lot quieter. I attribute most of that to the valve job because that is where most of the noise was coming from in the beginning.
I went for a ride to make sure nothing was going to go wrong before I took off on my way to work in the morning. The white spacer mod helped out with the backfires, either that or the dang carb was so dirty that it was leaning the mixture out. I am going to have to mess around with the mixture screw again.
I got back and noticed an occasional "knock". My hypochondriac self also heard some chain noise, but I think that is a figment of my imagination. It does seem like there is a lot of noise coming from the front/front left side of the block. It was there before, but hard to pin down because of the valve noise.
The knock, however, seems to come from the right hand side, just below/front of the oil filter. It was hard to pin down, and I will do some more listening tomorrow, but I found it by sticking a screwdriver in between the oil filter cover and exhaust pipe.
I am really not too concerned, at this point I just want to ride, its amazing how much you miss it when you cannot do it. Its different when you just don't have the time or something.
Any clues what this engine noise is? Could it be coming from that one bearing/shaft that is just to the right of the cam chain? That would make sense why I hear the noise on the other side also and in the front. I am going to look over my engine diagram to try and see what it could be.
Just thought I would let you guys know you are great. You were a big help to me through this, and eventually when I get back in there to put in the verslavly. Next chapter is probably going to be cam chain replacement, hopefully not anything worse. Thanks again.
