Ok, I contacted the bloke about cams, and yes he has done some for the R3.
He was very open in his thoughts, and at the end of our conversation, here is where we are.
He claims without having a high compression engine (904 Big Bore) the results that he would come up with would be less than impressive, his comment was the bonnie engines are very under done. He also stated that it would cost about $A5000 to come up with the first cams, and unless there were definite buyers it would not be worth while. He is a one man operation and does not have the financial backing to do this without confirmed buyers.
I am not willing to spend $5000 to see if it works so at this stage I would suggest that the companies such as megacycle, and British Customs, who do make cams would be the best bet. And going on his thoughts, cams without having increased the compression on the engine would be less than inspiring.
Cheers,
Cruser
