Well, you probably picked two of the more difficult "EFI" bikes to deal with. Like everything, time has improved fuel injection systems in bikes and the 1000 v twin Suzuki's do NOT have the latest technology.
First they tend to be tuned on the lean side in the lower rpms and part throttle settings. This is all about emmissions. Common to have some lean surging, even backfiring and hesitation especially in low speed/load riding. The higher rpms and throttle settings are actually quite rich, which is common in OEM tuning to protect the engines.
Other than some inputs from air temp sensors, manifold pressure sensors, there is not much the system does to "tune" on the fly. It does not have the ability to read air/fuel mixtures and adjust.
Many owners end up going to a tuner, Yosh box or Power Commander. While there is some improvement with these, my opinion is that they really need to be dyno tuned to the bike to work right. If you do a precision tune up to the bike, in stock configuration, they can be made to run pretty smooth and strong.
I would still rather fool with the EFI than Carbs. I am from the "good ole days" and remember all about carbs. EFI is actually much easier to diagnose and fix IMO. Don't mention the improved starting, driveability, and fuel mileage. But, like everything, some tuning can't hurt! Good luck with your new Vee!
