    I will look through the album there is sure to be some of that day. I was with a group in the grandstand who saw the accident but realised the marshalls were unsighted so we leapt the fence trying to attract some reaction but with Cal prostrate he was basically invisible to them. Sadly while we attended to him the worst happened. He was a definite star to be. I spoke at length to him prior to the meeting and did take some photos of the bike so I will dig deep this week-end

    Thanks for that, the photos would be great, although he was riding a Suzuki that fateful race at Puke, some sources I have seen allege its the same bike Geoff Perry was killed on in Tahiti.

    It did say in the paper Cal hit some drums fill of water with his head,you say you went over the fence to help him did you see any drums at that part of the track.As for Geoff Perry my understanding is the plane he went down in the water, was so deep they could not get to them so thats where he rests today, if this is so very sad for his mum and dad not to get there son back.There is one of Geoff Perrys bikes at Len Southwards.

    I would be contacting Rob Ianucci - Team Obsolete....if they are still around?

    I read it quickly but I think it said there were 6 bikes.

    Why would you do that ? The bike was built in Adelaide, based around a set of Sportster cases in a featherbed frame. It has never been to the US, is not a factory bike and has never been raced : built as a tribute by the late Bob Jolly for Grey Chandler who has lamented for years that he didn't hang on to it.

    If I've read the thread correctly, then seaqnmac27 is looking for info on the original US built bike so that he can verify how close the replica is to the original.

    Do you actually know when it was built up for Grey Chandler? We are really trying to work out what sort of money this bike is worth, I suspect the current owner has a slightly overblown idea of its value, but any clues would be a huge help.

    Let's put the record straight. The XR750 tt was built by Myself with the help of Bob Jolly and Peter Taylor[ machinist ]. It was built with the approval of Harley Davidson Race Manager,Dick O'Brien. Who,by the way wished he could have used a similar frame, but was constrained by the regulations of the day. Thankfully we had a original XR750 to copy. This was on loan from Team Obsolete to be restored and was done by me along with building the my bike. This endeavor took 5 years and won the approval of Ron Alexander,Cal Rayborns chief engineer. We did a couple of sessions at Mallala where i rode it as well as Murray Johnson and Bob Jolly. All up a good bike all round and would easily run to 8000 + rpm . This was a mammoth project and would not have been possible without the talents of both Bob and Peter and the engine and gear box parts from Team Obsolete. We did the heads in house.That is another story !!! We took the factory bike to Phillip Island but it suffered catastrophic cam bearing failure. Hope this sorts out all the bullshit. cheers,Gray Chandler.

    I should add I suppose this is a replica built in Oz by Bob Jolly.

    References say Geoff Perry killed in plane crash not on a bike. I was a huge fan of his at the time and remember the news at the time. Check with Steve Holmes, he did a painting of him.

    I could be wrong, but I thought Geoff Perry and Alan Woolfs son John were both killed in the same plane crash.

    Steve, John Woolf and Grant Whitaker were unfortunately killed in a collision with a hunters 4 wheel drive that they meet on a blind crest in a rally in States, the hunters were also killed. This was a tragic accident and took two promising, charming young fellows from us (the NZ motorsport family)

    Wow, I'm impressed! How did you know that? Indeed I did do a painting of Geoff Perry for a guy to give to his son for his 21st birthday. The son's name is Perry, named after Geoff Perry.

    Yeah I know, it was clearly someone who did not know what they were talking about.

    I was at the same meeting, but over by the hairpin at the time. We were stunned! He was riding a local TR500 Suzuki running on methanol. Getting in his hand before taking up a Suzuki works ride. Not Geoff Perry's.
    Interestingly, a guy I worked with here in Perth, was at the same meeting (he also rode a TR500 Suzuki). He reckoned that Cal's mechanic adjusted the carbs, just before the race, but inadvertently leaned them out, as he would have on the Harley, instead of making it a bit richer. Lack of experience with 2 strokes?? The bike seized at speed.........!
