intake lift 8.8mm, same as 0.490"
exhaust valves 2x32mm, same as 1x1.78"
exhaust lift 8.3mm, same as 0.462"
inlet cam open 17 btdc, close 63 abdc.
exhaust cam open 53 bbdc, close 27 atdc.

I have been all over the internet and not found much at all, quite a lot of 250/300 stuff not much for the 650, thats one reason I came here, similar cylinder capacity.
