Nice! What is the bore size of the gsxr throttlebodies though? I'm not convinced that it is big enough to really support 2.4 litres of displacement. After all they were designed for 1000cc motors, that's less than 1/2 the displacement.
EDIT: I did a quick calculation and the numbers I came up with make me more suspicious.
2400cc x 7500rpm is 18million cc/min
1000cc x 15,000rpm is only 15million cc/min
According to those numbers the bore size of the gsxr throttlebodie is almost certainly not quite sufficient to support 2.4 litres of displacement. I don't know the redline of the gsxr off of the top of my head though so if it's higher than 15,000 rpm's then the numbers will get closer. Basically these numbers are just to compare approximately the maximim airflow that the throttlebodies were designed for to the maximum airflow needed for the extra displacement. These are just a tool to compare, not actual real numbers.
