I'm with anotherguy. Fire it up. Nothing sounds better than a raped ape Sporty.. My second street bike and first Harley was a 73 XLCH. Had a lot of good memories in the 10 years that I owned it. Regret selling it and wish I could get it back.. I slapped a S&S carb on it and that really helped eliminate the Sportster knee. I hope you get her going.
