I want a Harley some day

Well just like anything else you can make an H.D. very reliable. Here is my 1969 FLH. I've owned it since 1976. I ride it every day (weather permitting).
You can also make them run pretty good too. Here is a shot of my Sportster Super/Mod. It ran 9.30's @ 140 on all motor. This bike won 2 National Championships. My Evo powered Pro/Mod ran 8.80@ 150 also all motor.
