Update 2007 FLHTCUSE2 oil leak @ 3950 miles: After 9 days in the shop, I got my bike back last Thursday. There was a national backorder on one of the cylinders which is why the wait was so long. They had the bike back together the same day the cylinder arrived. When I went to pick up the bike it was spotless with no evidence of major work. I must say again, these guys at Billerica HD have been great so far. I got 2 new cylinder/piston/ring kits along with the latest gaskets. While they were working on the bike, they also noticed the rear axle adjuster was bent (not sure how or when that happened, may have come that way from the factory), so they went ahead and replaced the adjuster and axle shaft under warranty. I chatted with the service manager for awhile. He told me that they have done 4 of the cylinder/piston kit fixes for head gasket leaks, and have replaced 4 motors due to excessive crank run out/failure so far. He assured me that any future problems with my bike would be taken care of. I put around 280 miles on it so far and so far so good. I'll just keep an eye on the cylinders for oil leaks and keep riding it for now.
