How cool is that RS 750 of Freddie Spencers? Here's Bubba Shoberts later HRS 750 and under that, a poor boy Honda big bore tracker....a Trackmaster CB750 which I presume would be legal for the proposed Old School 'Twins' class.

 Aussie Luke Gough aboard the ultra trick Kawasaki 650R Ninja powered / Rick Howerton framed bike at the Springfield Mile. These new generation Japanese twins are starting to poke their nose into Harleys domination of the class.
                                             
                                                           
Check out this photo shootout between the Suzuki, Kawasaki, Triumph, Ducati, KTM and Harley. The bikes are getting complex but shouldn't be so hard to build one suitable for our conditions using a wrecker writeoff and some lateral thinking.

I saw that bike at Hondas US HQ in 1984 and had the $4,200 to buy a brand new motor, but I changed my mind after Gene Romero Explained what was really required and Gary Mathers really didn't want one in Australia.
 I then started to by an XR but was talked out of one of them by Ron Wood whose bikes are without doubt the best machine for our tracks, he was sponsoring a very young and extremely polite Chris Carr at the time.
We could fill this thread full of trick US Flattrackers but I would rather it be full of Australian bikes that will be ready to ride later this year.

During that trip I decided to buy a C&J horizontal for the XR500/600 but the wife found out before that happened,
Jay Foreman went back the next year to race the AMA and brought back one of those setup for the CR500,
I still have that bike, Casso ride it at Kempsey in the mid 90s, I crashed it big time at Barleigh Ranch but it has not been raced since cause nobody ever got it to handle,
That reminds me that Peter Goddard followed Jay to the US the following year and I think was the first Aussie to beat the Yanks at their own game.

Back in the early 80's I recall Ted and Peter Goddard turning up at Nepean with a very tricked out C&J XR500. I wonder where that bike is now?

There is lots of trick Flattrackers in Aussie sheds,
I hope they start coming out,
I had a look in my shed today for some parts and found a TM400 Flattrack frame,
That will be good to get ready as well.

sidecar road racers used to do that in the 1970's.. and i know of some historic roadrace XS650's and TX750's that have their cranks re-phased to 270 degree, same as a TRX850  :o

although i have no idea who they are or how they did it  ;)

Zak, check out the XS sites on google.
Mikes XS in the US has threads on how to do it though the usual way is to press the crank apart and then rotate it and press it back together. It doesn't give an exact 270 though. To do that you have to get tricky and do it properly :D
We have a kid up here that is actaually numbered 270 on his Wasp and ha has done it all himself and it can fearly fly. Worst thing is it sounds not unlike a 500 single-just you can't catch the bugger :D :D :D
