Love your safety gear Rog.
i had one of those and so did the MXTV Telletubbie (Macca) we both raced them in C grade MX, enduro's and trail rides. I loved mine so much i bought the 85' model after i dropped the valves at Sea Lake Desert race in 84' and got it all fixed under warranty would you believe
and By The Way, Macca and I shared a house together for a year or 2 in the 80's, we have known each other for 27 years
