Sul sul! Here are some default replacements for the motojacket and motopants combinations. I'm still focusing on other defaults first, but I thought I would get some separates out of the way.

aftopmotojacket replaced with @nonsensical-pixels' 4t2 Conversion of mellosaki's Trad Goth Jacket and @goatskickin' edit of deedee's 4t2 leather jacket. Enabled for YF & EF. I don't think I touched any other flags. It requires The Sims 2: Nightlife in order to work.

afbottommotopants replaced with @nonsensical-pixels' 4t2 Conversion of mellosaki's Gritty Bootcut Jeans and angelapleasant's 4t2 Conversion of Sentate's Mortimer Leggings (boots). Enabled for YF & EF. Flags are also unchanged and should be the same as the top. Normal shoes sound for the bootcut jeans, boots sounds for the leggings. It requires The Sims 2: Nightlife in order to work.

aftopmotojacket_ep7 replaced with @lucilla-sims' 4t2 Conversion of Maxis' EF26 HHC Jacket. I kept the blue butterfly swatch, but I replaced the other two swatches with the Get Famous version of this top (since its the exact same mesh, and I kind of prefer those swatches). Enabled for YF, unhidden but not townified out of personal preference (mostly due to it being a crop top and conflicting with some of my pants). It requires The Sims 2: Freetime in order to work.

afbottommotopants_ep7 replaced with @serabiet's mesh and texture edit of Whysim’s 4t2 Sondescent Quintuple Button shorts. Enabled for YF, unhidden but not townified to match the jacket, boots shoe sound. It requires The Sims 2: Freetime in order to work.

aftopmotojacket_ep8 replaced with @monilisasims' 4t2 Conversion of Sentate's Bella Jacket. Enabled for YF, unhidden. This one is townified since the seams work nicely with pretty much everything I have downloaded, so it should work with (most, but probably not all) outfits. It requires The Sims 2: Apartment Life in order to work.
