I started riding in 1974 on a CL100 Honda.
My 3rd street bike was a red 1975 400F.
I did most of the small mods myself, I had a Boston Cycles mechanic who raced install a Yosh cam and then had Performance Engineering in Brighton re-jet and synch the carbs.
I installed a Lockhard oil cooler, Koni shocks, 15 weight fork oil, K-81 Dunlaps, and a color matched Camber1/4 fairing. I was setting the bike up for Mod-Prod and Endurance Racing.
I ran into Johnny Bettencourt in the pits at Daytona in 1976. He had a blue 1975 400F with a color matched 1/4 fairing that his cute girlfriend was riding in Florida. He was racing for Yoshimura East at the time. One of those KZ900s with gobs of horsepower and flexi frames!
Anyhow, we got to talking about the 400Fs. I had just ordered my fairing at a show in Daytona but the tinted windscreen was on back order. Johnny offered to loan me his spare clear windscreen. That was wicked cool of him. I rode that bike around for several months with his windscreen on it until mine came in and I drove down to Bridgewater to return his.
Too bad he got so f***ed up on coke. He was easily one of the nicest and most talented riders I have known.
I have owned dozens of bikes. And while the 400F was not the best bike I owned, it was and still is my favorite street bike.
