Okay, as I have said earlier, I am new to the airhead world just acquiring an '81 R100RT. I bought new Metzlers at Motorcycle Superstore and took them to be installed by a fellow Patriot Guard member that has a motorcycle shop. He called me and asked if I knew that the old wheels and tires had tubes installed. I told him no, and that I thought the wheels were set up for tubeless tires, but I deferred to what he found when he removed the old tires. I thought the so called "snowflake" wheels were tubeless rims. Anyone with more knowledge than me care to comment? I went ahead and had him put tubes back in with the new tires. This old girl keeps throwing me curves as I restore her.
