adopted the "formula" structure, which allowed 2-strokes and 4-strokes to compete on a more even basis. He acquired a Ducati 750 Imola Desmo which he raced successfully through 1990. In 1991 he bought a 1990 Ducati 888 SP2. With its electronic ignition and electronic fuel injection, this brought his professional expertise to the race track. He was one of the first privateers with his own chip writer. In parallel with racing modern bikes, he also raced vintage bikes, mostly English and Italian bikes from the 1950s and 1960s. He raced both new and old bikes through 2000, saying "I’ll keep at it as long as it is fun". Regretting the bikes he sold when he left England, and determined not to make the same mistake again, he kept all but two of the bikes he bought in the US, and bought back "Father William" in 1993, ending up with 40 motorcycles, which he kept in a milking parlour and hay barn attached to the house. Gunn also owned a few classic cars, including a 1929 supercharged 1750 SS Alfa and a 1971Datsun 240Z. In April 1972, Gunn paid $10,000 for Ferrari 375 MM chassis No. s/n 0382 AM, the ninth and last of the 1953 4.5litre V12 spyder series cars built for racing in 1954. Built originally for American semi-professional racer Bill Spear, after competing in SCAA events in the hands of various owner/drivers, Gunn competed in the car for the 1972 and 1973 events, before retiring the by then non-working car to his collection. After Gunn's death in 2008, his three daughters sold the car to noted Ferrari collector Andreas Mohringer of Austria. After refurbishment and then display at the Pebble Beach concourse event, it was shipped back to Paul Russell's shop in New England.
