Back to FXR's..........
Mine is a 1992 FXRS with about 135,000 miles on it. I say about, because I had a problem with the speedo cable breaking and probably put about 2K on it with no speedo. (Turned out the nut the cable went through on the back of the speedo had partially backed out- easy fix once discovered) It still has the original drive belt, clutch, brake rotors, engine mounts, paint, and so on. I didn't have any real problems with it til 50K when I had to replace the stator and voltage regulator. It has an EV13 cam, which is a wonderful cam for just waking up the Evo without hurting gas mileage, Crane lifters (two OEM lifters have failed, luckily without trashing the engine or oil pump), SE adj pushrods, SE air cleaner, and Dyno Power slip-on mufflers on stock headers with crossover. The base gaskets were replaced with James metal ones at 65K, along with new rings and head gaskets as long as it was apart. Torrington inside cam bearing, of course, and the tranny sprocket with the wider splines. Had to replace the starter clutch at 110K?, put in a solenoid rebuild kit sometime or other, probably other stuff that I can't remember right now.
I get 47 to 51 mpg, burn no noticeable amount of oil........
Almost forgot one of the best changes. After an idiot trashed my front forks with her uninsured car, I got Progressive fork springs and added their 411 shocks shortly after that. What a difference from stock! I thought it rode and handled well before, but it's a whole new bike these past few years with the Progressive suspension. And it's not a big expense, either, $90 or so for the fork springs and $170 or so for the shocks.
I have a National Cycles compact HD style windshield and Wild Willie saddlebags and a cheap but not bad-looking travel trunk on the luggage rack. It's definitely a touring machine and the stock seat is still comfortable for all day riding.
I think it's the overall best bike Harley ever made. I wouldn't dream of replacing it with a current Harley. With its cool-running Evo with the far superior twin tapered Timken main engine bearings, and the superior three point rubber engine mounts, this bike should still be going long after the disposable twinkies have all bit the dust.
