I suppose it just seemed like the thing to do at the time.I had been tinkering with a buddies 63/72/74 combo Sportster/ chopper looking thing and I was checking into some parts when I stumbled across an old '83 Sportster, mostly original, in dire need of some TLC... rough looking ole unit that has been sitting for awhile but i picked it up cheap. I think it has a lot of potential.
