GSXR 750 Throttlebodies
Anyone know or know where to find out the max flow rate of the injectors that suzuki fit to these?

I have a feeling it's 250cc but don't quote me on that!

supposed to be good for up to around 200bhp so 250cc would be about right.

Thanks. Looks like 240cc/min. Unless anyone knows different!

I've actually measured the flow rate from the GSXR600 bodies and injectors I'm using, was pleasantly surprised to find that the figure was
320cc/min, this using a pressure regulator from a GXSR750. I wouldn't think the injectors on the 750 would be any less than this.
Bike throttle bodies tend to be bigger than car ones of equal BHP, because of the higher revs involved. This means they get a MUCH shorter time to get
their requisite squirt of fuel into the cylinder, and still remain inside a 100% duty cycle at WOT.
