I have been looking at the head and a question springs to mind.
The Throttle bodies are of a zx10r and they come in two banks of two and the pitch is 84mm
The pitch of the Cylinders is around 90mm which dosent give alot of offset for swirl would it be beneficial to?
A.put the two halves of the bodies at a slight angle to each other as viewed from above maybe 4or 5 degrees just to get a bit more of a swirl effect.
B.Not worry about it as it aint gona make a huge difference as the small 6mm offset will do the job ok.
Cheers fellas Oz
