Think I remember correctly - Jotas were mythology in Oz during the time they were well on the map with Slaters in the UK. I met a pommie guy in about 1977 who had a silver UK Jota here. It was legendary stuff. It would have done really well against the Japanese opposition at that time ... but you had to find the right rider.
We raced a 1200 in the 4-Hour in Perth (probably more as a showcase that a real threat) and I don't think Stanco had even imported a Jota until 1979 or 1980(?). I would have much preferred to race a Jota in 1978 but regardless, I was a C-grader and my boss who co-rode was not fast, and the bike was too slow in a straight line to really compete - so even if we'd ridden a Jota the hot shots from 'over east' on basically factory backed Japanese bikes would have won. With a really good A-grader it would have been a different story. The broken 3-2-2 collector was a minor hitch, but the broken x-over gear linkage was more of a hindrance. Just teething probs on a bike straight off the showroom floor.
You have to remember that proddy racing in Oz was HUGE and the Japanese factories were more than willing to give any assistance necessary to dealer teams (who spent PLENTY!). As Lee says, Stance had zip interest in real racing, so it makes it all the more amazing what Pete W AND TTM did in Qld - just wish he'd been brought further south - or west, to co-ride with me on a Jota!!
