In 1922 Gus rode a Sun Vitesse in the TT 250cc Lightweight class but over-lightening of engine components gave rise to excessive vibration, which caused the fuel lines to fracture. Nevertheless Gus and W J Lord finished in 12th and 13th places after wrapping handkerchiefs around the fuel pipes to staunch the leaking. [Thanks to www.cybermotorcycle.com for this information]

This picture shows the 1922 Sun TT team from L to R: W J Lord, Gus Kuhn, John Duffy *, M Bishop and Bernard Caldwell, the reserve rider.
