I am experiencing a yellow mottled discoloration on the front cylinder head pipe of my 09 Star 1100 that started around 300 miles. It starts at the flange down to just below the first bend. I took it in for the first service and questioned the dealer as everyone is telling me I have a problem with that cylinder and fuel flow. The dealers mechanic advised this was normal. The owner agreed with me, but also with the mechanic when he said it was normal because of the tight engine and I had gotten it hot during a parade or I had left the choke on to long during a warm up. I told him the discoloration happened before I was in the parade, and when it started giving me problem, I left the parade and rode to cool it down, but the exhaust was discolored prior to this. He gave me a small bottle of "blue away" and said to try it. The salesman commented that he has not seen one blue like this, just at the area of the flange and a couple of inches out but I had mentioned I was going to replace the exhaust anyhow. I looked at a few star 650's that stopped by and they had it just at the flange area of the head pipe. There were no 1100's to compare it with that day. Should I be concerned?, my friends who have all had Harley's say it is a problem with the cylinder running lean or something. Any other 1100 owners have this going on? I do plan on replacing the pipe in within the next 6-8 months with the DG Hardkrome 2-1 Sideburner but I don't want something happening down the road because of this. Any info would be helpful.
