BMW R100 ENGINE • $2,000 • FOR SALE • BMW R100 engine, purchased for $4,000 in 2022 (used). My father was intending to use it in a Mark IV build before he passed away. I have sale records, but as it is a motorcycle engine I have no log book. I am not a mechanic, so I've included pictures of what I believe is a vacuum pump that goes with the engine. Feel free to correct me if I am wrong. Text or email with questions and I'll do my best to answer. Engine is located in Potsdam, NY. • Contact Paul Kundrat , Owner - located Elgin, IL 60120 United States • Telephone: ---------- • Posted July 29, 2025 • Show all Ads posted by this Advertiser • Recommend This Ad to a Friend • Email Advertiser • Save to Watchlist • Report This Ad • View Larger Images
