After listening to warnings about removing the crankcase breather box and airbox and fitting pod filters, I did it anyway!
What the hell...its all reversible, and I don't routinely use all the power that my S4R makes anyway. Breather box removal requires making a small bracket for bolting up the voltage regulator.
With some help from Superjohn (thanks!!), I also replaced the left-side throttle body bracket with a home-made one which I fashioned from aluminium and polished a bit. Its fitment required removing the TPS, and I used the newly acquired VDST software to reset the TPS.
In addition, I relocated the starter solenoid (mounted where the right-hand post for the airbox was) and trimmed the bracket that held the solenoid -- cleaning up the look on the right side.
After everything was bolted up, it fired up on the first push of the starter button!!
