Hello Airhead enthusiasts. I recently bought a 1979 R100S. It is a fun ride and makes me remember what attracted me to the marque in the first place. My first motorcycle was a 1973 1/2 R75/5 which I rode for many miles and many years before giving it to another enthusiast to be reborn as a vintage racer. But it has been a few years since I kept up on the current state of Airhead maintenance and improvements. Luckily this R100S has already had some of the improvements I recall being suggested such as the 1981 Brembo brake conversion, stainless steel brake lines, and Dyna III ignition.
Last weekend I noticed the right side muffler is deteriorating on the inside. So I will be replacing the mufflers in the coming months. I understand I can still get BMW mufflers. I also see Epco Stainless Steel mufflers advertised in my Owners News.
Anyone have suggestions on the strengths and considerations for which muffler option to go for?
