Yeah, and once upon a time I had a high-maintenance girlfriend too. There's much to be said for not being high-strung and high-maintenance.
2010 FLHX (Surprise!) -- 96 in. engine, SE Stage I intake, K&N (like blowing your nose!), and 2 into 1 Nightstick exhaust. I added a digital temp/oil level dipstick, just because it seemed like a good idea. Then engine, even in streakin' hot weather, runs about 240F at the high end. Plenty of power, ample torque, good acceleration. I get a nice smooth power band from about 3K up to whatever (where I never go). Decent mileage, idles smoothly.
I tour on this bike. Rarely do I run less than 100 miles on any ride. Much of the time we're topping 500 miles, 700 miles in a day. One up, w/ luggage for camping on the road. I'm "haulin' freight" -- not racing or squirrlin' . . .
The 96 in. engine runs no cats -- that helps keep it cool. It's reliable as hell, and not going to burn out early because it's over-bored, over compressed, running lean fuel.
Like comfortable old shoes, a nice ride that I don't need to fuss over.
