The last time I saw a green H2 in Warragul, was in 1979. I was riding a Suzuki GT750M from Melbourne to Bairnsdale. (200`miles, but no freeways back then so we went thru every little town along the way) I'd already had a 10 mile impromptu drag race with an older guy in a V8 Ford LTD, and was just settling down to semi-legal speeds again when a guy on a hotted up H2 screamed past.
Well I had to chase him of course, so sat up his arse until we got to Warragul, where he pulled over, so wanting to check out his bike, I did too. He was wearing an Army Greatcoat (no decent bike clothing available back then, so great coats and flying boots were all the rage) and in his pockets he had around 20 spark plugs. While we were chatting, he was picking thru the cleanest 3 sparkplugs he had and installed them, then we took off again. He'd told me that he'd done some porting and had made his own expansion chambers, but the jetting was too rich, so he was doing a plug change around every 100 miles.
We had a great ride, averaging 100 MPH out on the highway and only slowing down for towns. Even though we both had to stop twice for fuel, I did 200 miles in 2 hours and 40 minutes, still the fastest trip I've ever done to Bairnsdale.
