You may have seen earlier posts that had bike in for head gasket leak in rear cylinder and originally thought crank might be out. Here is resolution - crank is reported to be OK; both head gaskets, rear cylinder & piston replaced, AND installed D&D Fatcats, roll-your-own a/c, and dyno tuned with sert.
Today is first ride except for home from dealer and all I can say is WOW what a difference this made. Brian Rose of Bumpus H-D did the tune and got 106 ft lbs of torque flat as a pancake from 2,400 to 4,600 rpm and you can really tell it. And motor is noticeably cooler.
Headed out to join HOG Posse Ride and covered 392 miles today - all interstate. Checked mileage on one 140 stretch where I ran 80 mph the whole time - two up pulling Bushtec trailer loaded to the gills I got 33 mpg. I'm happy with that. I know without the trailer and at more sedate speed the mileage will be great.
So all in all, I am HAPPY!
