I just turned 194,500mi. on my 2000. I have not had the top end off since I did the conversion. Technically, the bottom has about 165,000mi (bad oil pump).
2000 XLHC 883/1200. After seven Kawi's and 4-5 misc's. First Harley.
Invalidated warranty at 5,000mi. Thunderstorm/Andrews/Crane/Wiseco 10:1/Vance-Hines. Dyno 81hp. Just hit the button and go.
