I've collected for so many years - and recently sold a lot of my parts. I remember buying a DC carburetor for $5 bucks, one for $10 bucks - with a reply of "What are you gonna do with that?" Owned about 20 Sportster Buddy Seats - (but they never really took off). Now I'm happy with just a few spares. I stopped buying parts that don't wear out . . . instead I'm collecting clutch plates, tire tubes, bearings, pistons and rings. Next will be throttle cables, then more tires. Chains and sprockets. You get the drift . . . but, I still slip-off-the-wagon now and then.SEE ABOVE PHOTO: Recently purchased Tillotson velocity stack and aluminum XLR fork tube caps !
